I was told that his 91 has
a Banks turbo with no waste gate
3" down pipe with a 4" exhaust system Muffler delete
Hypermax inter cooler
air intake below the windshield on the cowling.
It has a throttle position sensor on the pump (????)
He has some concerns, they are
At wide open throttle he still has no smoke.
He says that it'll on boost 6 psi under any condition and it drops off quickly
(I told him that sounds like an air leak)
EGTs are never more than 600*
Ideas, comments, suggestions please
and Thanks

In hopes of more information. He's a recovering Cheby man and doesn't know much about what it bought.

he will have to turn the mechanical injector pump up to get more smoke/power. since those trucks where designed to run with out a turbo the after maket ones are set up to give very little boost he may see a little more lbs of boost once he get that baby burning a little fuel.

heres a step by step link I found. How to turn up fuel on 6.9/7.3 IDI - The Diesel Garage Forums

GET ER DONE!

might also check for exhaust leaks that will cut your boost numbers down real quick.
