Normal boost pressure???

What is normal boost on these trucks? I have a minimax, dpf/cat delete, cai. I run on no power setting and never see more than about 23-24. Is this normal? I read about guys pushing 40 on stock motors??? I haven't seen any codes or any evidence of loosing pressure through piping.

I'm having a hard time figuring out if I have a problem or not. Just went for a test drive. Hard on the throttle in both stock mode and Hot. Stock was about 31-32. Hot was 37-38. But it was not without trying. Seems like it builds higher the faster speeds I go. I'm used to getting boost compared to the load its under. Like when I'm pulling my tractor, not based on speed. I'm still new to sequential and variable geometry turbos, so maybe this is normal. I've driven semi's quite a bit and they build pressure under the load. Please let me know if I'm wrong on what to expect.

That sounds pretty normal to me. Maybe other will chime in.
