I didn't find any definite answers thru searching, so thought I would ask.
I have an 05 Silverado with a stock 5.3. I'm looking to add a Procharger P1SC to it. I have a head unit from my old Firebird, and can easily mount it with a mounting plate from Brute Speed. My question is what boost pressure is everyone running, with/without intercooler, and what pulley size?
I have an Alky Control (methanol injection) system from the Firebird, and was wondering if I could save on intercooler system as long as boost didn't get to high for stock 5.3 with no intercooler?

I would think you could do 5 lbs without an ic. More with meth.

I would do a small front mount air to air, you will want to run more boost at some point.

Just do a intercooler you will be glad you did.
