i would take the edge off and retry it and would put a pressur only box in it's place that should help

Are you running anything to get rid of the anti de-fueling? a smarty or a BD-rad box?



not sure on the 3rd gen but i believe the truck is de-fueling in 1st and 2nd gear,



2nd gen's do it also.

What year is your truck?

The torq management is holding the boost at 15psi with the brakes locked.

15psi is quite a bit of boost for a 4wd and most 2wd brakes won't hold this much. With most street turbos 15lbs is enough for them to spool instantly. the torq management keeps you from breaking too many parts.
