Low boost after ebpv delete

Guys,

Truck is a late 99, 6speed, 4" turbo-back, 6637, gauges, canned tune (on truck when purchased.)

Last weekend i had my truck apart to fix a bunch of leaks. (turbo pedestal, hpop lines, fuel bowl, etc.)

While we had the turbo off, we decided to gut the turbo pedestal and weld up the holes.

Got everything back together, fired right up and idle great. By this time it was late so we just cleaned up and called it a night.

I stopped the next day to pick it up, got to talking with my buddy who helped me do it. He took it for a drive and made sure it wasnt leaking any fluids.

Heres the problem, before teardown and the ebpv delete, my truck made 24lbs at WOT. Now the truck ONLY makes 15lbs at WOT. Thows no codes, motor sounds normal, etc.

Does anyone have any ideas what could cause this?

Yeah, something is loose. Intake spyder, intercooler boot, something. Double check it all. Check to make sure you plugged the little line on the map sensor back in.

Ohh wait, someone already said that.

Nonconformist. Functionality over bling.

My three rules for 7.3l troubleshooting: 1) Replace CPS and keep a spare. 2) Replace FPR and know your fuel pressure. 3) Hook it to a scanner and check for codes.
