Customer Testimonials

Darrell - 2007 Yamaha FJR1300 - New Brunswick, New Jersey

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 this guy named JEFFO. I decided to give him a call and see what he had to say. Well I got Jeffo on the phone and he explained the process of what he does and how he can save me time and money. Long short... I bought a map.. installed it and the bike is running way better then stock. It pulls stronger..seems to be smoother on the highway and gas mileage did not suffer! I never write testimonials but I thought Jeffo deserved a shout out!
