1996 psd no power on startup

Ok I have a 1996 psd with intake, 4" staight pipe, and PHP 6 position chip. Recently when I start the truck with the engine cold its has no power. It does not matter what time of day or the temperature outside. If I start it with cold engine it sounds like the ebpv is on. However It has been unplugged for 6 months and the problem just started. I have also removed the tube and cleaned it with no change of performance. When the truck runs like this sometimes it will clear up in a couple minutes and sometimes i can let it warm up for 15 minutes and drive it 5 miles before it changes. When it starts to run correctly, It acts like I just flipped a switch and the truck runs like a bat out of hell. When it is acting up it will not gain rpms past around 1800 and wont hardly go faster then 30 mph. I have tried to run the truck with it in all the positions of the chip including stock, and there is no change. please help

You can't "unplug" the valve, since it's mechanical. You might have unplugged the sensor and/or the actuator, but unless you _wired_ the valve in the open position, it can close on its own. Make sure it's actually physically open.

if that "sorts" the problem out...how big of a job (and how much $$) is it to "delete" the valve all together

Undo the V-Clamp holding the down pipe to the turbine outlet and separate them to look inside. On top of the outlet there is what looks like a brass freeze plug. Directly opposite, under the outlet, is the actuator rod from the pedestal to the butterfly vale in the exhaust. remove the rod by pulling straight down. Look inside the outlet and rotate the "arm" under the outlet till the EBPV until it is completely open. wire the "arm" to the pedestal in this position. Reinstall the down pipe. wire up the rod so that it is straight out of the pedestal like it was still connected to the "arm". The rod has a wiper seal at the pedestal that you don't want to provide a side load on or it will leak oil.

If you have a torch just cut out the butterfly inside the outlet tube (remove it first from the turbo). Pull out the upper and lower pieces of the shaft that held the butterfly. Tap the holes that the shaft came out of. Insert plugs into the tapped holes to seal. You will still need to gut and seal the pedestal so that future leaks from here don't happen. you can do this yourself with some epoxy or you can buy a EBPV delete pedestal ($200)
