I bought a power commander V because I was told id have access to hundreds of maps. Well that was a lie, they didn't have a map compatible with my set up. I did many searches on custom map tuning and tried to contact other tuning companies. Jeffo is the only one that has taken time to even help me. .....Read More
There's a saying that if you want something done right you do it yourself. But when it comes to building a map for your PowerCommander there is no one better than Jeffo. I have bought 3 maps for my own bikes and 7 more for a few of my friends and people's bikes that I work on. Every person who ri.....Read More
This testimonial is well overdue. Jeffo's custom tunes are AMAZING!!! After submitting the info for my bike I received it about 2 hrs later. Jeffo called me after sending me my tune and explained everything to me over the phone to ensure that I understand the instructions he sent with my tune. After.....Read More
Well jeffomaps came through again for Me with my new side x side a 2018 wildcat xx! I recently added aftermarket muffler from speedwerx, s&b air filter and PCV. The map I got from speedwerx was not exactly right for my setup! Well I finally got to get out on some wooded trails and some fire roads to.....Read More
I was searching the CBR1000 forums and came around everyone talking about this guy named "Jeffo." He builds custom tunes for street bikes and the such. Just so happened that I had just purchased a PC3. Man, let me tell you, I had never downloaded a motorcycle fuel map. But Jeffo walked me through it.....Read More
After spending hours upon hours researching the best ways to improve my bike, I came across Jeffo through a simple google search. Not only did his custom maps improve the quality and performance of MY ride, but his service also includes countless tips and suggestions on simple but effective mods tha.....Read More
This man Jeffo has so much race experience he built me a map in 45 min that runs flawlessly. He also took the time to teach me how to use the PC5 and the different options and features such as the Accel pump options. I don't have any Dyno graphs to prove the performance gain but on my fully stock .....Read More
I found Jeffo through the zx-14 forums, while searching for info on my autotune I saw mention of his maps. After requesting info we spent talking and he took the time to explain everything to me and why I was having a hard time with my current setup. We worked out two maps, for now!! I loaded the su.....Read More
Bought myself a new '19 zx6r and added an aftermarket air filter and Graves slip-on. Pretty basic mods so I was hoping it would run fine without needing a tune. Lots of varying opinions, but I found that I lost throttle response and I knew it was running lean which could lead to future issues. Plus .....Read More
I tried install the stock map from the Dyno website and I just wasn't happy with it. After calling around I found that getting a tune was going to cost way more than I wanted to spend so I decided to do a quick web search and stumbles upon Jeffomaps. Jeffo called me within an hour of submitting a re.....Read More
Bike runs just like Jeffo said it would. Its like riding a new bike, love the new map. He picked up all my phone calls and help me on the things I could not figure out thank u again I am truly happy with everything!
I originally thought I needed to get this bike on a dyno to get the maximum power out of it. I wasn't planning on going on the track to race, so I thought I would give Jeffomaps a try. Well I'll say I would be satisfied going on the track with this map Jeffo made. It runs like a beast ! I feel like .....Read More
I Read some reviews and decided to give it a try, I'll tell ya it's well worth the price and power to fuel mileage ratio, this bike goes like a raped ape and you gotta hang on tight now!
Holy s&@! Jeffo is legit! His tune took my bike from mild to wild. Pulls hard off the start and still has plenty of power in 6th gear when you crank on the throttle. Don't waste your time or money with dynos, Jeffo knows what he is doing
Thanks for the incredible map you made, my bike runs smoother, pulls harder, and sounds perfect...best performance mod I've invested in so far...I cant wait to do the sprocket upgrade...feels like a whole new bike!
Ok, I'm not the type of person to do this but I really want to express my thanks to Jeffo. I bought a PC5 for my 2000 Kawasaki ZX-12R. I down loaded and install one of the maps for my bike that best fit what I have. It did improve the bike performance better then it was at first, but it still didn't.....Read More
I was searching for a Dyno tuner for the new power commander 5 that was recently installed on my bike. While searching the different forums I came across a post where a guy claimed he had a custom map installed without the expense of a Dyno. I was skeptical but kept reading different posts about thi.....Read More
I've gotta admit power commander generic maps are complete crap but there is Jeffomaps that is by far the best bang for buck at a quality service. I thought that I was getting a small improvement but I got a huge improvement the throttle is more defined alot smoother not touchy like it was before, p.....Read More
This is the second map from jeffomaps and probably not the last. Its a great cost effective way to improve your bikes fueling. His map made my old ZX-10R run better than it ever has and he will sort out any issues you have straight away. Thanks Jeffo!
If you are looking for a map for your bike I wouldn't go past JeffoMaps Following Jeffo's instructions my ZX-14 has a significant increase in low rpm range and feels like a new bike. I will be recommending Jeffo to all my riding friends.
Thought I had to spend a good $350-400+ dollars to put my bike on a dyno to get the performance that I wanted. I was wrong , I came across Jeffo maps and figured I would give it a shot , sent him all the info required and received my map that night. Very clear and concise intructions , great custome.....Read More
Got everything installed and running (super easy with the detailed instructions). Went on a 2 hour ride. It runs like a champ, like a completely different bike. Thank you so much for all the help. I have attached a picture of the bike and testimonial is below. After owning a 1979 Suzuki GS1000 .....Read More
Great customer service. Easy instructions, bike is running great
Great tune with to the "T" instructions, bike runs like a dream. Thanks Jeffo, great product and great service!!
Got my map within 24 hours and it came with specific instructions, the bike runs great has more power and flys on the top end.
Let me start off by admitting that I myself rarely leave reviews on my experiences (good nor bad). However, I was compelled to share my experience with Jeffomaps for the simple fact that I was given solid, sound, and verifiable information that absolutely enhanced the performance of my Ducati 899. J.....Read More
If you guys and girls haven't pulled the trigger on one of his custom maps, DO IT! my old beater has never ran better nor stronger. I recently did the recommended NGK plugs and Shell gas. The bike starts quicker and idles better now. I'm very pleased with my purchase. Thanks again.
The mapping worked great, very helpful, big difference between dyno jet maps.I still have some things to get from the list of suggestions, but already running much stronger thank you.
Hi Jeffo I wanted to say thanks I installed your map today. It's easily the best $110 I've spent so far (exchange rate is not good at the moment) my bike is running heaps better a lot smoother better acceleration it'll be interesting seeing the difference next time I'm out with the boys on their Har.....Read More
I'm very impressed and well worth it. The map opened up the power to my track bike. Way better and smoother then the free downloads. I could feel the difference right off the bat. Jeffo is also very easy to work with and easy to get a hold of if any questions come up with the install. Instructions a.....Read More
Wanted to thank Jeffo for a great street map, with all the great suggestions that he made to make it a beast ! I would highly recommend Jeffo to family and friends.
Just wanted to thank Jeffo for a beast map. I would highly recommend it.
Jeffo maps is EXACTLY as advertised!!! Definitely unlocked a whole new monster in my 2014 R1. The bike I knew is gone! If I was married, I would now be divorced because I have fallen in love all over again with my bike! The communication is off the scale and he returns calls and texts almost instant.....Read More
Picked up my dream bike and immediately fell in love with it. Just needed to fix a few things... One of them being the powerband. The previous owner claimed they had the bike dyno tuned with the PCV installed. I have no proof of this, so I went with his word. I noticed that all the power seemed to b.....Read More
Hey to anyone reading this I'm gonna start off by saying I'm a real person and no one paid nor asked me to write a testimony. Jeffo provides facts! I'm thankful I called and told all my friends about him. At the time I was just going thru forums trying to find different ways to just get a little bit.....Read More
I am so very excited to post my testimony about the level of service and the quality of the tune I received! Guys trust me when I tell you that you are wasting your time and money going to other places that only want what you have in your pockets! Jeffo is a god among tuners and will not only turn y.....Read More
I have to take my hat off to this man Jeffo his work is second to none. This was by far the best money I spent on the bike the difference was unbelievable. I have a CBR1000RR 2007 model which made 158.2 hp with 129.3 ft-lb of torque with the factory tune and after Jeffo worked his magic on the map i.....Read More
I have a 03 Kawasaki zx6r that had a custom dyno map I had done for $300. Jeffo you are the man I just got everything loaded on my bike today and took it for a ride. I got almost 200 miles out of my tank of gas. The throttle response is so much smoother. And power gains all the way through my rpm ra.....Read More
I ordered a map for my 04 cbr600rr,Not only did he call and talk to me about things,also emailed me a list of things,answered my questions when ever I had any. Huge improvements on his map over stock. I highly recommend his maps! Well worth the money! Love it!
Hey Jeffo. I finally got some riding time in with the new map and I love it! I must admit, I was a bit unsure there was a significant difference at first. I actually had to load the old map back in, ride around with it for a bit and then load yours back in to really tell and boy did I notice a diffe.....Read More
Let me first say the map has turned the ZX14 into the bike it should have been. Finally it runs the way i'd dream't that it should run. Beautifully responsive on the throttle (smooth as glass), no deceleration popping. The torque and power comes on from the very beginning of the throttle and pulls h.....Read More
Thanks for making my bike (2007 R1) running more responsive and cooler. Bike also doesn't run real rich anymore as it did with the other maps from Dynojet.
Built a custom map for my 07 Repsol 1000RR. That's all I expected for $50 but I got much more than that. Not only did he build my map...he recommended several other mods to perform based on my setup and what I was wanting my bike to do. I performed and installed the mods even down to the gas he said.....Read More
Having not been entirely pleased with maps I've gotten from Dynojet or http://z1000.riderdestination.com/thumbnails.php?album=7 I took some advice of some Z forum members and tried out a tune from this guy http://www.faic.cc/index3.html. Basically you submit all your performance related mods, normal.....Read More
After trying several “custom” dyno prepared maps on my Aprilia, all of which created their own set of operational problems, I located Jeffo on the internet. Shortly into the first of many telephone conversations with him I realized that he did not simply do maps he LIVES maps and performance. To say.....Read More
MAN!! Was tuning and tinkering with the dang map on my ZX12r. Ran a few Brocks maps…nothing but issues. Got a hold of Jeffo and what a world of difference in expertise and customer service. He had me a custom map by lunch time, And WOW he dialed it in right off the bat……Big difference in the way my .....Read More
Got the map installed the next day. Good instructions and paper work. They helped a bunch. When your new map took over you could immediately tell the difference. ZX-14 now sould and runs better than it ever has. Have over 500 miles on the new map and only smiles. Thanks for taking the time on the ph.....Read More
Just installed Jeffo's map today and man am I more than happy with the results. Instantly noticed hope much smoother my throttle response felt off the line and literally could feel an increased pull through the gears and RPM ranges. I can't wait to get to the track and see how it acts while I hammer.....Read More
I have a 2009 Kawasaki Ninja 650 and have the Arrow slip-on exhaust installed. I've been having lots of popping and backfiring when decelerating and rolling on the throttle. I decided to purchase a Power Commander V but I still needed a custom map. After reading several forum threads I decided to gi.....Read More
This guy really knows his stuff. Jeffo gives you great advice on how to make your bike perform to its fullest. I would totally recommend his services, he also assisted me when i needed information and he worked through any problems that I may have had. Jeffo is a stand up guy and I am very satisifie.....Read More
I am very happy with the way my '05 Ducati 999 runs! Its not running rich anymore and no one behind me anymore tells me that my bike smells like pure gas. The bike wants to pop up immediately when I hit the throttle and I absolutely love it. The Ducati shop here charges way to much and he did above .....Read More
I am very very happy with the map that was made for my '07 Ducati 1098. I had a map on there that was running rich and sluggish as hell. When Jeffo made my map and sent it over to me, the moment I hit send to my PC the idle in my bike changed was more smooth sounding. I love the way my bike runs and.....Read More
I recently submitted a request for a map for my 2009 Kawisaki Ninja 650R. Within 24 hours Jeffo contacted me for additional information and mods for my bike. Completed the full purchase a couple days later and received the map and set-up instructions within 12 hours. Installed the map several days l.....Read More
BEST $50.00 EVER SPENT PERIOD. i have a 2009 zx 14 after running a pc v with the dynojet map i was not impressed it ran real rich and had jumpy powerbands after seing a post on a zx forum and the 6 page thread with all good comments i had to try i emailed jeffo and got a response within hours sent h.....Read More
All I have to say is, "WOW," and even though I know it's cliche to say it, I have to: I was very skeptical at first, especially after hearing about Jeffo from someone I did not know on a forum that I visit. But I took a chance thinking, "Hey, it's 50$, if anything, maybe I will learn something. If n.....Read More
I was not looking for the absolute most horsepower from my bike. I wanted a bike that ran smooth, clean and crisp from idle to the upper RPM's. Jeffo’s map for my bike, an '07 CBR1000, was close to perfect! After talking with Jeffo several times, he is a very professional businessman that cares abou.....Read More
I don't know how this guy does what he does...but he ain't selling snake oil here!!!! I could not believe the difference in my ZX 14. It really is like a different bike. It runs smoother, pulls way harder, shifts better, and no popping. When I say it pulls harder I don't mean slightly either. WAY ha.....Read More
First I’d like to say “Thank You Jeffo” for all your assistance! The customer service that Jeffo provides is phenomenal! I myself was skeptical about purchasing a map file from the internet… But I am so glad I did! And for only $50. Jeffo sent me the map and explained how to set everything up like t.....Read More
I had been reading about Jeffo's tunes on the forums and figured why not try it. All I have to say is WOW!!! After loading it up my ZX14 runs amazing. The power curve is so smooth and I'm now getting all the power out of her that it was missing. To top it all off is the customer service. Jeffo spent.....Read More
Thanks, Jeffo. My bike is an 08 ZX 14 SE with a new Power Commander FIVE, catalytic convertor removed from stock header, Yosh R77 slip ons, K & N air filter. Where I live is about 3,300 feet above sea level. Ordered your custom map, incredibly quick phone and e mail response, followed your instructi.....Read More
Hello Jeffo! Okay-my zx14 "was" running good. I installed your map. I'm not sure now if someone switched bikes on me or not? This baby is everything I REALLY wanted in a Big, Fast, Powerful sportbike. No lie-she's running much cooler. Throttle response is NOW immediate. Cruising at slower speeds, sm.....Read More
I just wanted to let you know that the map you sent for my 2007 ZX-14 makes it run BEAUTIFULLY. The throttle response is much smoother and there is MUCH more power. The difference is like night and day. I went for my third ride with your map yesterday -- over 300 miles. I have 12K miles on the bike .....Read More
I ordered a map from Jeffo. Recieved a phone call from and we spoke at length about needs. I received the map that afternoon with all the directions. I installed the new map, set up the fuel pump utility and reset the TPS. Long story short I have a new bike. The map was spot on the first go round, s.....Read More
What can I say? Threw the map in. Set up the TPS and Fuel Pump. We tweaked it over two phone calls for my particular needs. And that's all folks. I'm extremely pleased. Try it, you'll like it!
Man I swear to you guys that this guy knows what he is doing! I sent in a request and immediately after I got a call back. Very good customer service.. And if your new to the power commander and its maps, he will also provide a step by step process to help you set your map. Believe me, he saved me f.....Read More
With in 2 hours of talking to Jeffo I received my new custom map for my 08 ZX-14. His instructions were very thorough and easy to understand. Before the new map my bike was running a little rough and sluggish in the low end with the muzzy map that was installed on my pc III. It was also backfiring a.....Read More
Just wanted to share my experience I had doing business with Jeffo . I placed my order for a map for my 08 zx14se within 12 hrs I was talking to him on my cell talking about the mods and any other issues I was having with the DJ map I had. Within an hr of our conversation I had a map waiting for me .....Read More
Jeffo’s maps perform outstanding on my 09 600rr. He worked with me through the whole process of tuning the PC5 fuel map and other adjustments adjustments in the few places required based on my riding style (I tend to sit a little higher in the RPM range than some people). Even more important than th.....Read More
I searched the net aimlessly for hours in search of a map for my Yamaha Roadliner. I was getting the sinking feeling that I would have to dyno test my bike. I finally found the F.A.I.C. Website and sent in a request. In less than an hour I not only received an email from Jeffo but a phone call from .....Read More
Jeffo can work magic on your bike that you will not believe nor will you be disappointed in. I had tried multiple different maps on my 2008 R1 and just wasn’t quite satisfied. I found this website while searching for PC3 maps and submitted the info on my bike. Jeffo responded within half a day on a .....Read More
First I’d like to say thanks for all your help. I’ve tried other maps and haven’t been happy with the results and was at the point of pulling the Power Commander off the bike. I thought about having a custom map made from a dyno shop, but was hesitant about spending $250-$350 dollars. I found your w.....Read More
Jeffo, I don't know how you did it but WOW! I've finally managed to get out on my Busa, the temp today is a balmy 4 deg C! The bike ran like never before, smooth power delivery from zero to 11000, fantastic, no glitches low down, no surging high up, even tick over in fact PERFECT, the bike has been .....Read More
I was looking for a EFI map for my 08 SV650S w/a Yosh RS3 slip on. The Power Commander site sucked (it only has 5 maps and none had Yosh pipes listed),SO I HEAR ABOUT Jeffo on a blog site and visited his site and read about his maps. I emailed him some questions and within hours he replied that "he .....Read More
As i begin I’m asking myself why am i writing this testimony, i want to keep this secret arsenal of custom tuning to myself, to hell with the others I love smoking the unsuspecting people that think their bikes are fast. I happen to have the total package of having the only 600cc bike in the world w.....Read More
Excellent! Thanks Jeffo, I'm very happy with my new map - Stronger, smoother power from the bottom of the range to the top. The flat spot I used to have at 5000rpm is gone too. The fueling feels perfect. Highly recommended. Suzuki SV1000S.
Let me start by saying that I've been riding on the street for 11 years and counting. Two of those recent years were spent teaching with CCS, locally. The bike I am currently riding was my former race bike, a Honda '05 CBR600RR. So let’s just say I have quite a "mod" list. I have never had a "custom.....Read More
My name is Jeff and I talked to you at the Pavilions on Sat. You also adjusted the map on my CBR1000RR, which after the ride home, you should have seen the smile on my face. It is awesome. Lets just say the front end now easily comes up at 95mph+. (On the track of course)
Thanks for making my bike (2004 Honda RC51) run better than ever before! After I installed the Power Commander PC3-USB and the 2 into 1 Jardine exhaust, I experimented with many different maps offered by other major exhaust manufacturers. None of them even came close to the smooth linear power deliv.....Read More
With my maps, my bike runs much cooler and I make more HP & TQ, and much better gas mileage on my 2004 Aprila Tuono Factory Racing.
Thanks! I'm very happy with your map file for my 2006 Kawasaki ZX-14. Rideability is excellent. I'm getting about 2 more MPG and my bike is running 1 bar cooler on temp, too. I dyno'd with both your map file and your F.A.I.C. Sportbike Mid-pipe and muffler and got about 8 more HP and 5 more TQ.
