I keep reading these post that say I hit 140 and I kept wondering how? Sorry guys but had it on the dyno and 140 is not happening. Your speedo my say 140 but your top speed is 127 in 4th. We tried it in 5th and the speed limiter kicks in way before that. I am not saying that it wont do 140 but you will have to find a way around the speed limiter. If you don't believe me take yours to a dyno and see how far off your speedometer is.
