Its a waste of money for a Cobb AP. I see everyone get this cause they didnt know any better. Just about all the new cars are coming with open ECU programs. Cobb says its great cause you can take it off anytime. All it is, is a big waste of money. Get to a good tuner/Dyno and have it reflashed youll be better off and you can use the money you would have spent or already spent on an access port for a really good tune.
