Exclamation 97 psd loss of power when in passing gear

hey all. 1997 psd 4x4 straight 4 inch pipe all stock. my truck lost its normal power when passing someone, at WOT it feels like it is starving for fuel. when I sit in park and rev it up, normally it would let me tach it out, now it starvs at 2600. I looked through all the threads and gcould not find one that really pin pointed the problem. I think it could be fuel pump?? Any help would be awesome! Thanks

change your fuel filter and clean the fpr screen if you havnt yet. That could help. Good luck!

Could be the issue, I would check oil pressure, the low pressure oil pump might be starving the HPOP resivoir.

I'm troubleshooting the same problem. So far, I received the following suggestions:
fuel filter (done)
air filter (done)
MAP sensor (done)
thermostat - low temps causing EBPV actuation?
turbo

The first three things still haven't fixed my problem. Next step is the thermostat since I'm pretty sure it's stuck open right now anyway.

just unplug the ebpv to see if thats your problem... its a 2 wire plugin underneither your turbo inlet...mines been unplugged for almost a year with out any problems.

I unplugged the EBPV - didn't really seem to make much of a difference. Someone else suggested fuel delivery or oil. That would make some sense since I'm not able to get any black smoke from the exhaust no matter how hard I stomp on it.
