Cruizin Posted May 1, 2015 Share Posted May 1, 2015 Stock Exhaust before and after flash +4 HP! http://i.imgur.com/117vS45.png M-4 Exhaust Baffle in Before and after Flash +7 HP! http://i.imgur.com/bL0PwoL.png So, a healthy HP gain for both stock and M-4 Exhausts plus, the flash fixes the loss in bottom end torque when you change exhausts! Plus, people are reporting such smooth engine response all the way across the board with these tunes! Great work Nels! As always. This is the way the FJ-09 would be if Yamaha didn't have to play emissions games with bikes.
