Customer Testimonials

Tom - Yamaha R6 - Tucson, Arizona

As i begin I’m asking myself why am i writing this testimony, i want to keep this secret arsenal of custom tuning to myself, to hell with the others I love smoking the unsuspecting people that think their bikes are fast. I happen to have the total package of having the only 600cc bike in the world with Jeffo’s muffler and patent mid-pipe design, and a fully custom map by Jeffo so honestly I’m not too worried of being beat by another 600. I can go on forever about the fact that my bike runs cooler, crisper throttle response that still catches me off guard in the corners...SOME OF YOU HAVE WITNESSED LOL! Simply put when you smoke a guy that’s given it everything his poorly designed map has... on your FREAKING back tire through 4th gear! JEFFOS maps WORK! Get hooked up with his bad ass custom maps or F-OFF! while you’re stuck jacking off in the shower thinking about watching my shift light come on as I’m SMOKING YOUR CRAPPY MAP!!!
