It’s plenty high. My drive pressures are 2:1 boost not
Going any higher until I do a non VGT swap on it down the road.

I think at the end of the track testing & tuning day. Becca's going to want more boost.
Might as well go ahead and throw on those compound turbo's. Happy wife, happy life. :rofl: :D

Keith, toss an S475 over top of the VGT and have fun. I've heard a lot of people say that brings their drive pressure down

Oh it will but it also brings lag. Right now I have boost within 5feet. I am going to adjust it more and bring boost In just a touch later and that will lower drive pressure some too. For right now it’s working great and it’s very sporty for a diesel truck.

Swap truck down! Went to take off from a stop sign today went about 6’ and zing the trans let go engine free revved up. Well now it’s time to step it up a little anyway. Getting a free 47rh that will be stage 3/4 built and triple disc lockup converter. Also swapping in a 11.75” rear diff with 3:42 gears so should be able to ride around 1200 rpm at 70mpg lol.
