I'm suprised RX-KEVIN hasn't replied to this post, but I have the HKS SSQBOV. Get new turbo piping for the t-flange it will come with (that plastic has gotta go!). Don't try to do some kind of adapter to try and fit the stock plastic piping, pointless. As of PSI settings I'm ok at 9. You'll pretty much be making a lot of adjustments to the HKS BOV when you first get it though (I did mine during dyno test, is pain in a$$). You'll definitely like the results. Boost controller is nice but it's virtually pointless until you get a bigger intercooler and better downpipe, cat, and exhaust (plugging spool-turbo.com here). Fuel/air settings? I'll talk to my mechanic when I get a chance, he has all that info documented somewhere. OR RX-KEVIN can show up out of nowhere and give that answer.
