Will the MM3 measure boost pressure?
If so, where?

Yes it does.
You have to go into the pressure option on the dashboard screen in the MM3.

Yeah, I found how to get into them by trial and error. So many things that can be changed I'm scared to mess with them.
I do wonder if my truck bucking and rpms bouncing could be corrected with timing, but I don't know where to begin

I had a max boost at 40 psi on lowest tune, is that normal?

Not usually, no, I think the highest I've seen is 37 or 38 psi, but really any thing at that or after that pressure is not very efficient from what I've heard, maybe someone else will chime in more on that.

Boost pressure is monitored by the MAP sensor which maxes out at 37-38 psi.
I have not heard of one reading beyond this.
The stock charger is only good/stays in the cool air MAP until about 32psi so anything more than that is asking for issues.
are you running stock VGT charger?
