Customer Testimonials

Aaron - 2005 Honda CBR600RR - Dover, Delaware

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 on it. My 05 CBR600RR and I are 120% satisfied! Thank you very much.
