368rwhp on stock 5.6psi is actually great numbers IMO. you also have to look at the fact that you gained power throughout your whole rpm band. With some sort of timing control and 8 psi you will easly make the 400rwhp + club. I would not be disapointed with those numbers. Remember test pipes and exhaust would of only gained you 5-7rwhp at best on a NA setup. Great setup !!
