That's quite a big difference given the rev limiter is at 11k and I'm definitely hitting it (got it on video here)

The Sat Nav said 121mph afterwards. I've been playing with that app you mentioned but that's suggesting a speed of over 140mph on that gearing and that clearly isn't right. Are you supposed to change the numbers in the boxes next to each gear, and if so how do you know what to put in there?
