This is my first 6.4, what I'm wondering is what I can run on boost and egts. I bought a 08 6.4 with a new motor and tranny. The motor has h11 head studs and deliped Mahal pistons, new fuel pump fuel with the 150 air dog, wicked wheels in the turbo and a ton of other stuff. I have the boost set at 42 lbs now and the piro set at 1350, how far can I push it when I get it broke in? Only has 1700 miles on it so far and getting 20 miles to the gallon on highway with the high setting on the mini max box tune with 37's on the truck.
