Default Procharger Pulley Help really quick.....

I am running too low of boost on my TBSS setup. I am looking to be a bit higher. WIth a 4" pulley on my P1SC I am seeing around 2lbs of boost at 4,000 RPM's will not see 3 until after 4800 and 4 at 5600 or so. I peak at almost redline around 5.5lbs at 6,000 rpms. I ma wanting to bump that up a bit and am wondering what size to go with. I was thinking a 3.7", I ultimitly want to be around 7-8 on my LS2 block. Some of you who run though alot of different pulleys should be able to help me out here. Everything is stock on the truck, Meth is in the future but not on yet. I do have a cam as well but I want the blower working where I want it first. I want to get my pulley on order so I can get this project done.

Thanks guys.

That 3.7 pulley should get you in the 7 range. You will need a tune though.

I am running a 3.85 with my mods and seeing 7PSI. Are you running an 8rib setup? The 6ribs have a different pulley size for the crank.
