If any of you guys are running the stock vw t3 and want to try my merc compressor housing and wheel for a few dyno runs to map the difference I might be talked into shipping it up as a loaner for test purposes. See my post in the idi section about compressor upgrades. It would be good if you had the correct guage setups so could compare boost, egt etc.I am guessing you might need to adjust fuel to take advantage of the greater (fingers crossed) boost. Let me know, Jim
