typical boost levels

OK information please.....

what are the normal boost levels fora 7.3 with no chip or reprogramming, i do have the 6673 filter, and a 4" exhaust on my truck now which is a 2000 4x4. I get about nominal boost at cruising speeds, and when I am accelerating at about 2000 rpm low load i see 7-8 and then up to 17 in a really hard push. anyone else have something to chime in with and will disconnectin the waste gate tube affect it greatly?

A max of 17psi is normal on a stock truck. You're right where you should be.

I got around 17, then I cleaned my boots when I did the foil delete and that brought it up to 20.

I could hit 30# with my stock turbo, before the TN turbo and injectors. Everything in my sig without the turbo and injectors.

With the below mods, I'm hitting 28ish, and it was about the same with the stock turbo, but with A LOT higher EGTs, especially on the top end.

I haven't run it hard while looking at the boost, and only WOT twice. I know playing around I can hit 33 kind of easy.
