Engine/Transmission (1998.5 - 2002) No power after startup

[paniolo]

Aloha! I got a 02 6spd, twins, comp box, injectors, intake, exhaust, inline exhaust brake, aux. fuel pump. Its a on and off thing. After startup upon acceleration there is no power. Seems to just bog down big time. After a min. its full power no problem. Any ideas? Thanks

Is the exhaust brake sticking closed? Might be a bad APPS/TPS. Do you have any codes?

Thanks AKAMAC funny you say that. Another site said the same. By the way I did cycle the BD inline exhaust brake and it did cure the problem. No codes just throttle boggs down. After a min. works fine. I activate the brake several times a day to keep the build up down.

I think you posted this on bd, I think you may have way to much fuel pressure from what yo usaid on the bd forum.

Try to deal with one demon, another one pops up. Fuel pressure wise.

Messed with comp box, exhaust brake seems ok. Wondering could it be one of the turbos sticking? Defective, not enough oil or something? After intial startup bogging truck runs fine 45-50 psi. boost. One day gotta pull off the tubes and free spin the compressor wheels after truck been sitting.
