I recently Purchased and installed AAM Short tails, and when i press gas somewhere between 2.5k-3k rpm just shoots up to 6k-6.5k rpm. what is causing this. short tails is the only thing done to the car so far. its 7A/t transmission. what can be done to fix this, i have read that Tune might fix this but i have no clue where to start at. any suggestions will be really helpful thank you everyone.
