lower the fuel pressure 1 or 2 psi to get your A/F a little leaner.

Wow thanks for all the responses I guess I dont feel to bad about only making 295 whp, the dyno was done on a dynojet. The motor is completely stock which means it still has the stock headgasket so im a little worried about boosting too much, next thing on my list is to replace the cams and put a new headgasket it, I just wanted to see where I was at before I started to go any further.
The power started to drop off at about 7000 rpms, but the afrs dipped down to around 10.8 from 11.5.
Im going through the car today to check for any problems boost leaks, timing, and bumpin the fuel pressure down, I have an safc2 as well so I can lean it out and get it a little better. I have an aem wideband so I can adjust the fuel as I go.

Don't worry about the head gasket the stock one is good. Just add the s3r cams and fine tune the a/f.

how much boost can the stock one handle? I tested the compression recently and it was good. what about some stage 2 bcs?

how much boost depends on the tune. It will take 30psi with race gas and a good tune. 20psi on pump gas.
