I have this problem with all of the tunes. Right now I'm using the MPG boost tune. Between 4500rpm and 5000rpm the power fades and feels like it's surging. I've had this problem for a while, happens under load almost every time from 2nd gear to third.

This does not happen with the stock tune.

The log shows the throttle angle bouncing around...not sure why. Shouldn't it be smooth?

I will post a log.

Thank you.
