Customer Testimonials
Thoris Johnson - 2012 Kawasaki ZX14R - Little Elm, TEXAS
I was initially using a canned PC5 map off of Dyno Jet's website for a exhaust system that was similar to the one on my bike. I contacted Jeffo through his website and provided all details about my bike and within 2 hours I had a fuel map that was tailored specifically for my bike. I'm a very satisfied customer who was a little hesitant at first that a bike's fueling can be tuned over the internet. Boy was I wrong! First the throttle response is perfect with increased acceleration across the entire RPM range. My butt dyno indicates I picked a few ponies in the lower/middle range. Also the decelerations pops have significantly decreased which indicates to me that the AFR has been improved. I must say that for the price and the results delivered versus getting my bike dyno tuned, his services were well worth it. As a matter of fact I'm so impressed, that I will be seeking out Jeffo services to tune my Gen 5 ZX10R once I completed with my mods.
