Nick - 2019 Honda CBR650R - Chicago, Illinois

I wanted to write this much earlier, but I was too busy enjoying my new PC5 map/settings on my 2019 Honda CBR650R. I bought this bike to get back into motorcycling thinking I would just cruise around on the street. Jump to one year and thousands of dollars in performance mods later, and I was in need of a custom map to tie all of those modifications together for the track. "Off the shelf" maps just weren't going to cut it and I wanted to be more involved/knowledgeable than having a tuner do everything for me. Working with Jeffo was a total joy and he got back to me so quickly. He answered all of the question that I had and I could tell he really wanted me to be happy about my setup. He takes all elements of AFR into account and walks you through the whole integration so if something isn't perfect, it's probably user error, not Jeffo. My bike now runs to its full potential and I would highly reccomend Jeffo maps to anyone looking for: Affordable and effective. -Nick
