Hmm my steeda tune has some "RPM hang" but I don't know what you mean by that. Does it happen all the time or just sometimes? Sometimes when using the manual selector and than after switching to drive will keep the car in whatever gear i had it manually in, than it shifts very firm into the next gear. It's jolting, but happens only occasionally. is this what your referring to? doesn't happen in drive only manual selector than going to drive.
