No check engine light even hooked in my code reader... nothing at all. I will try to hook up a gauge to the schrader valve to monitir it while driving. I did hook up to my 40 ft travel trailer that weighs in at 9200 lbs last weekend and pulling it i didnt get much boost until around 2000 rpm in any gear at all. forget about going into 5th gear even on level road it wouldnt go over 50 mph, i am getting boost because i can hear the turbo whine. but i did notice under load it appears to have a miss. no codes so i dont know how to track down a bad injector or injector wiring.
fuel pressure isn't monitored by the PCM, so chances are good that could be your issue.
Has the fuel bowl regulator ever been rebuilt? Has the fuel bowl screen ever been cleaned?
