A lot of that makes sense, kinda like we were texting about. A setup that flows better wil flow the same amount of air, but with less resistance will end up being a lower pressure (psi).

The whole compression ratio thing, that really seems like such a tiny change that I wouldn't have imagined it would have done anything like dropping a whole psi. Doesn't seem like that much "bigger" of a chamber with lower compression pistons. The cam makes a lot of sense I think, but for some reason I was under the impression that your new supercharger cam was less aggressive than your NA one was. Also makes sense your motor is still new and fresh, might take a little bit to break in / wear in. All just speculation as I'm hardly an expert on any of this by any means, lol.

EIther way, as long as you aren't finding anything 'wrong' then hey that's all great news. Who cares if it makes a PSI less, and a few HP less (hell that could just be a difference in the dyno itself). That's a solid number, on a fairly light weight car. Enjoy that beast!!!
