They sound about right for a pre-turbo probe Pyro 24 valve Cummins.

does the boost sound right or is this little low

Mechanos

The boost gauge is basically a "gettin' it" gauge. If you are cruisin' along with throttle barely cracked and not working the engine, then the boost will be really low like that. Now, when you turn onto the accleration ramp to the freeway and punch it, you should be building much more boost there. Max. is about 20 psi +/- for a stock wastegated turbo.

Drop 'bout 15,000 pounds worth of trailer behind the truck and see what happens to those boost numbers.
On level ground, at cruise, my boost numbers are pretty low too.
Keeping the boost numbers low will help get better fuel milage.

If I hammer the loud pedal under load, I'll see ~ 27 pounds.

You must be talking about the autometer steering column pod yeah I agree if it would replace and not overlay that would be nice.
