Just started tuning on my own for this pulling season. Just got back from a test in tune and truck ran like poo. In the off season I put a different intake on and decided not to use the mafs. In my log file the the truck never commanded more than 10200psi of rail pressure. Question is does the default -40 degrree that the truck now reads cause this issue.(On an Lb7 mafs and iat are the same sensor)
