ypu are in the 94-97 forum as well, but we can still point you in the right direction. Do you have gauges or use software to monitor the truck? Have you seen a drop in boost or increase in EGTs? Boost leaks are not your friend. I would start there and check your IC boots and the intake plenums for leaks. There are several good threads on how to build an adapter that goes on your intake and use an air compressor to build pressure, then use soapy water to check for leaks. If you look at the IC boots and they look oily then they may be leaking
