It is now obvious I need a retune. My opinion is, Allen, doing the right thing, was way too conservative on my mail order tune. I don't blame him. Without the dyno results you could hurt the motor.
8psi sts, non intercooled, 2800 tci stall, injectors, fuel pump.

I'm not sure how far you are from Allen, but being able to sit in the truck goes a helluva way towards a better tune -- even if he doesn't get her on the dyno.
Turbos can be tricky to tune -- lots of factors in the equation. Make sure you can check your KR, your fuel pressure, your boost (assuming you have a boost gauge and are not going on what the spring should be giving you).
I ran 7.5psi without meth on higher compression, but I tuned for it.
Are you able to log? That will also help Allen out if you can't get to him.

Could this have anything to do with the traction control (if so equipped) not allowing the truck to go into power enrichment? If you have TC, turn it off before you run. Seems to make a difference on my Tahoe, on the street anyway, I haven't made it to the track yet

they put down great numbers on the track also.....get with allen and see what he thinks bout your problem...i think you need a meth kit to get you temps down so it doesnt pull so much timing from the motor...dont know unless your logging the info thou...
