From reading the various posts it appears that if I select long-tube headers that my car will require a tune. What is meant by "tune"? Does it entail flashing the ECU or/and reprogramming it to accomodate the new headers?
AND, if that is the case who do you trust to do the tune? I asked a couple of dealers and they would not do it. Do I find a tuner shop to tune the car? Are aftermarket shops equipped to deal with any error codes, etc?
