i have a stage 2 HRC fmic, im only hitting 6 psi.. i want 7~8, shuldnt it alreays be set for this? or will i need an MBC?

I don't remember what the wastegate is set to, maybe your boost gauge is off. Anyways if you want to turn up the boost a MBC is your best bet. You may have lost a psi or so through the intercooler. Has anyone ever actually measured the drop? I'm gonna do that eventually.

I don't know about the hahn kit, but with my star I have a 7psi spring in my tial wg and I see 6psi. I'd say its just the drop from the intercooler, like BlackMagic said, the easiest way is to get a MBC, just don't go crazy with it or you'll be rebuilding sooner than you want to.

IIRC the stage 2 WGA is set at 9 PSI. With the Hahn FMIC I saw 7 PSI tops.

hmm, well when i got it from a second party, idk ifthey had a stage 1, then bought the upgrade, then id be runnign on a 5lb spring correct, then is it plausable im seeing 6 psi from a 5lb spring?

This wouldn't happen unless if your boost was creeping up to 6psi, so you would probably see about 4psi and then it would creep up to 6 as you continued accelerating.

As someone above said, with the 9psi spring the most they saw was 7psi Here's an idea too, if you haven't done so already, do a boost leak test. If you don't have a boost leak tester, and don't want to make one, then at least double check all your couplers and tighten them down again.

hah aim down for doin a boost leak, can you point me to a how on building one?
