Normal Boost Maximum for stock 325?

[MojaveJoe]

Well I just installed Edge's CTS2 gauge and learned my max boost on the street is around 34-35. Having had a 305 2004 Cummins previously I recall it running around 25 max. So Iam wondering if my gauge is reading properly at 35 max on this 2004.5 Cummins?
Getting ready for a cross country 12000 lb RV towing vacation and want to make sure everything is right.
Any and all advice and experiences welcome.

30-32 on my mechanical Isspro gauge.

Sounds right to me. Although admittedly if I'm on the throttle that hard I'm probably not looking at the boost gauge.

On my old '05 I saw the same as jgillot, it would spike to about 32, and then settle in around 30 or so.

35 is max boost on these turbos...I normally see between 28 and 32 if I have time to look at the analog gauge.

30-32 psi and settle at 30 psi with stock if the WG controller is still active. Turn it off or add a boost elbow and they will make 40 psi when you load it hard and run it out the back door.
