Same pulley. I have a boost gauge now that's not permanently mounted,
though it works (at least seems to). I was getting just a tad over 6 with
the stock pulley, and then I swapped pulley's and now it's a hair over 10.
I think the heads cam probably have something to do with it, there are
several other mods that will lower the apparent "Boost", however you are
still pumping that air through the system, just much more efficiently. From
what I understand the M1 Intake and Ported polished heads (esp big valve
types) will drop the apparent boost in your truck because they flow so much
better, I wouldn't sweat it cause it sounds like a good thing.

10PSI?
I have a 2.45" pulley and still only hit 9PSI... whats the trick to get the
boost?
I made 8PSI with a 2.70" pulley... so, there is a restriction in my system
somewhere, unless the heads/cam are killin my boost.. :-/
