I had the rod as tight as it gets and i was only seeing 32ish so i recently loosened it 13 turns. Yes the red vac. line is on it. But i cut the redline and put a home made manual boost controller their. i think the boost controller is crap cause my main problem is at 32lbs of boost it wont climb any more. You can just feel the power level off. Any ideas? No packpressure guage, what would i need that for? Thnks for the help
Exhaust backpressure is important because it lets you see how much differential pressure there is between boost and drive. Too much drive pressure will kill a turbocharger in very little time. If you don't know what it is, then you may never get your "problem" fixed.
What is magical about 37 PSI? More boost does not always equal more power. If your drive pressure is 50+ PSI (which I nearly guarantee it to be), then you're not doing your turbocharger any favors anyway and you're not making any more power.
I hate to ask if you've already said something about your current modifications, but if you're already running out of fuel, you're not going to get more boost.

Ever run one??? Its one of the best wastegate controlers on the market for our trucks...
10mm socket and an extention and I can ajust my max boost to what ever my injectors are capable of building.

I think thats it.I really doubt its the wastegate, tighten it back up, remove the blow off you have installed in the red line...
Do you have any kind of a Map fooler? I dont see that mentioned. Be it a blow off or a regulator.

Get a less restrictive turbine housing which would free up high-RPM power but possibly lower your boost a few PSI OR live with your present boost level, barring all other mechanical aspects of the truck are fine.
