I ran the stock program and here is what I got at WOT, engine Load 99%, RPM 2491, actual rail pressure 14854, desired rail pressure 15168, I got a call into the dealer to talk to them about it , this truck also never smokes no matter how much program I put into her, I was told MAF but would this tell the ecm to tell the cp3. their are no drive issues at all just low rail pressure but from what i am told I am supposed to have around 24k
