Im looking into possibly getting a tune (either SVT or 5 star) for my next upgrade but I have 0 experience with engine tunes. My question is will my truck pass emissions testing with a tune? Or will I have to reverse it back to stock before taking it in for testing? In Phoenix, we have some tough emissions laws & testing, which Im told is only exceeded by Southern California.
TIA
