Is this normal? I didnt reset the battery when I put it on, should I ? or will the ecu relearn to the new mod? Maybe the car really needs gearing now because of the 331s. Thanks guys!
No it won't hurt it. But it won't really do anything either. I would recommend reloading your tune, however. If anything would help, that will. But yeah, with 3.31's, you will notice a hit down low having an H pipe. But the sound is all worth it. If you're really worried about it, email Brent and tell him what's going on. Maybe he can tweak your tune.
