I'm not unfamiliar with a standalone system so that may be my first route. There's some place here in Utah, Turbolab, iirc, down in Provo that tunes boosted cars no matter the type, and there's another that does Vw's specifically. When I get to that point I may end up seeing what they think. I'll try and go down there sometime next week. I've been looking at the intake setup, I might end up having to find an Eaton m112 from a mustang or something, the M90 may end up a bit too small.
