gauges wired-need to check some baseline numbers
Well after getting the truck back from the tranny shop Wed ,spend fri installing pryo probe and new to me turbo .Then all day today installing gauges. So now everything on my sig is installed .Took her for a good run up a small pass held her at 70 for 1 mile up 4% @ 2000 rpm/15#boost/1000 egt and back up the other side same #'s these sound about right [virgin pump] at cruising speed very little boost unless i give it juice /pryo at 600[pre turbo] so these seem about right. ps isn't amazing how cheap a " new 1st gen truck" is these days

I don't know how much overlap the valves have so you might need to roll the engine over slightly but I didn't need to.
Then you just use soapy water on the suspects until you find bubbles.

I wouldn't be surprised if there's not enough fuel available to make more than 15 psi. He said the pump is stock, and if the throttle linkage is as sloppy as most he's not even getting all that is available. EGT is low too.
