10lbs of boost
i have a 96 12valve cummins the last month i have noticed low power installed gauges and been trying to figure it out i can only get about 10lbs at WOT hammering on it hard i have good fuel pressure at idle and it jumps up when revving idle it does not smoke and i clamped the wastegate with no change

It doesn't take much, but normally a boost leak is accompanied by lots more smoke and higher EGTs. I've had some pretty significant boost leaks though, and never lost more than 5psi off the top. Way more significant than some pin holes. I don't know what your issue is, but I think it's something else.

well i have good fuel pressure to the IP and only have those leaks wired the WG shut and still cant get over 10 lbs of boost no smoke either and highest my egts get are 1000 im at a loss this truck used to pull uphill with a good load on 70mph with the cruise set and not lose a mph now im lucky if im doing 55 by the top could it be the IP timing slipped
