Hey all, I have a 2011 6.7 cummins manual Trans. I have recently deleted, Airdog 165, s&b intake, 4 in turbo back exhaust, and efi live by kory willis. Oh and installed a clutch rated for 650 hp. All the other tunes work great except Max. In Maxx tune the fuel rail will only build up to 93 psi. In ecotow and street pressures jump to 102-103. La tuning(kory Willis) read my data logs and told me I have a problem with my truck. I don't understand why it would show in only one tune though. If the truck had an issue you would see and feel it in all the tunes. The truck just want go in maxx. It never boost up or nothing. Sometimes in all the tunes, if I stomp the throttle I get a perform service message on the evic. No dtc's though. Any input would be greatly appreciated. I paid for something that I would like to work.
