rpr said:Couple of questions:
1) Does using these tunes void any warranties?
2) Before I take my X in for dealer service, should I flash back to the stock programming?
1) Yes, the dealer might void the warranty for having an aftermarket tune on the motor. The reasoning is that if the program is altered from factory settings, they may say that you put a program in that is detrimental to the motor. Examples of this is an extremely lean tune that would burn the pistons or over agressive timing that causes detonation.
A lot of it depends upon the service department. I have seen cases where the warranty has not been voided, and other cases where it has been voided.
2) YOU BETCHA!!! Absolutely put it back to stock.
