Thanks. I've been wanting to knee him in the groin for about two years... that scumbag has probably paid off his M5 with the money I've spent on him doing mechanical "fixes" that will never fully solve the problem. I can't believe it. I can't believe I didn't see through his incompetence.
Do you (or anyone) know of any good tuners with a dyno in Southern CA? How much is this going to cost me?
