Customer Testimonials

Rich - 2018 Honda CBR600RR - Toms River, NJ

Did alot of work to bike but dynojet map was not doing it for me. Bought 2 maps from Jeffo 1 winter and 1 summer map installed into PC and made the adjustments Jeffo recommended and the bike came alive. Smooth, responsive, no temp issues, sounds and runs great. And his customer service is outstanding. Gladly answers any question you have quickly and by phone. He called me and helped me while he was shopping. You don't get better customer service or a quicker response than from Jeffo. I'm 52 and used alot of companies over the years so i would know. Thanks Jeffo for everything and thanks for saving me a lot of money that I don't have to waste on a dynotune.
