I have a question regarding with ECU Reflash, all the reflash option R1, R2 and R3 show only the top speed, but I can not find acceleration improvement, for example, in the Yamaha site, FZR from 0 to 30 mph in 1.3 seconds. How compare the reflash to stock, from 0 -30, 0- 40, 0- 50, 0-60 and 0- 70 (0- 80 only for reflash ECU).
