So i have an 06 procharged 10psi and everything with the diablo tune, and i wont go into how my car wont run right cause of crappy tuning. So im going to get myself an XCT II and get a nice custom tune from either Brenspeed or JDM Engineering...i know they both have amazing tunes for natually aspirated stangs, but my question is, How are they with supercharged tunes?? also, does anyone make an aftremarket like high performance MAF??
