One of my issues, when i'm in 3rd or 4th (didn't noticed it on other gear) i have a point between 3000 and 4000 rpm where the acceleration reduce then goes up again. According to the FAQ i found here, the problem come from the grounding apparently. Did i understand correctly ? Do you know where i could find a detail explication on how to solve this ?
