Thinking it might be a temporary solution to get rid of my trumpeting until I have a chance to buy and install some resonators. I was thinking of lowering them just enough so it stays out of the RPM range. Would that even work? Would it destroy the performance? It only does it in 1st and 2nd and just before it shifts.

 

im not sure on the changing the shift points, but you could just shift manually if you want to stay out of that range.
