stock paxton Boost nuumer

What is the normal boost for the stock pullies on a typical setup...

Or what would you say on this:
Boss Manifold, JLT Intake, LT & no cats full exhaust at 7500 rpm.

Trying to figure out some pulley sizes and waste gate or remove when switching to e85.
Stock internals with billet OPG & sprocket

I'm around 8.5 with similar set up.
I'm about to install a return fuel system along with the torque booster kit with
.33 pulley on e85. I'm very curious as to see what changes it's going to bring.
I'm going to use the 10lb spring

Only 8.5 psi on stock 3.8....
I thought it was more like 10-11 in the 7400rpm

I think if you look at the description on beefcakes or Paxton's site it states 7.5-8.5. I think I hit 8.5ish. I'll have to record my gauge and watch it closer.
You might see a bit more than that but not much.
