I just recently put ARP studs, egr delete, 4 inch ehaust and an SCT X3 tuner with innovative diesel street tune and im only doing about 30 lbs boost at WOT. and that just doesnt seem right but i may be wrong. Anybody else doin more than me with the same mods?

That sounds about right.Is the tune old? Eric writes them for stock studs and gaskets. Call him and tell him you got studs and he should be able to write you a new one. Can push more boost, but your numbers sound about right to me.

mine pushes about 22-24 at WOT. The truck got a new turbo when its was about a year old and when ford replaced it they reprogrammed the truck so it wasnt pushing as much boost. Before that happened it was pushing about 36

My 06 Studs,egr delete and Erics tunes 28-30 psi Was normal,If you were pulling a hill with the converter locked somtimes it would go higher....And Eric is known for making more power with less boost on 6.0!

On a stock turbo...To much boost and it is like pulling a pin on a grenade. 30-33 is pretty good above that I would watch for dents in the hood

The 03 turbos are a different animal, they have the loudest whiste on any 6 liter, could be the reason it also pushes more boost, too much boost is deadly for 6 liters even with head studs, pushing over 40 you will soon see engine parts sticking through the hood, 30 boost is good, 35 boost is high, 40 boost start taking out your wallet :)

I have been pulling my truck throughout the summer and I do some pretty heavy hauling with it too. (03 6.0) At times, when pulling I will launch the truck at about 18-20 lbs. and I have seen 40+ psi down the track. Turbo does have some work done to it and running Matt's Tunes. Nevertheless, I too had a FICM problem couple years back and waffled my stock IC. Went with a Hypermax now. I can see 30-35lbs. no problem. My two cents.

On stock tuning with my stock turbo I got to 28-29 at the most. With the race tune in it would go to 31. Sometimes it would hit 32 with a trailer behind it but thats the most I've seen with a stock turbo.
