I have a 2008 6.4l with a EGR & DPF delete. I had head studs done, SCT innovated diesel programmer and a cold air intake. The truck at 1/4 throttle will push 25 - 30+ psi boost but it is not applied boost or it will boost all the time. I does not blow off intercooler tubes off even at 60 psi. Sometimes it operates properly but for the most of the time you have to watch your boost gauge closely. It has cut my mileage in half since the dealer overhauled the truck. The code that comes up is P2263 so if anyone has any ideas email me back.
