Right... my understanding is just the air intake which didn’t make sense to me either. I don’t have the means to jack the car and verify stock DP. Anyone know of another way to be sure? Otherwise I’ll have to run down to a shop. Sounds like I’ll just grab a catted DP (if still stock) then flash with BM3 stage 1/2 93. I just worry I won’t have a stock tune back up at that point.
