The shop says the UpRev tune will eventually go back to the original settings ( ie- I will eventually lose the tuning anyways ) Since it's all bolt ons and ( I've already got K&N dual Ram intakes ), what do you guys think. Spend $700 for a tune? Or save the $ for the next set of tires I'll need? Any help is appreciated. Thx
