ok so it's not a rev limiter but it feels like it. I tuned a 2010 camaro with a built 376, mast everything, mid sized cam, etc. the car runs great at part throttle and full throttle and idle.
under specific circumstances it feels like it breaks up or hits the rev limiter.
it is part throttle, 3000-3500 rpms, by 4000 it cleans up and is ok again. full throttle pulls clean all the way through....
any suggestions? mechanical or tune? not seeing any knock during this event.
Post the log and tune.

IF YOU WANT HELP, POST A FILE!
I will post when I can. also, mast put in non stock coils and tr7 plugs.... maybe stock coils and a step hotter is in order? it's not a strange combination and the tune is not uh, experimental, pretty basic stuff.
