With high compression your are already generating alot of heat and adding an additional 20psi is going to blow the VQ37 to kingdomcome. I think the most boost you can run on the VQ37 from what I've read is around 8psi max on 93 oct. and that's considered high. When I had my Evo I was running 22psi daily driven and 24psi when in race mode all on 93octane.hehe.
Just curious, how did the Mitsu engine hold up under 22psi/24psi? Any smoke coming out of the exhaust that was maybe darker then usual? I wish I had a dime for every Evo and WRX I've seen over the past few years that were burning oil at an alarming rate.
