there was a thread a while back that pointed out that the setup for external wastegate was wrong and people could not get it to work. Well, I got the external wastegate hook up with the profec b spec2 to work perfectly. Those that have this EBC recall that for external wastegates you hook up COM and NC ports and leave NO open. This by greddy instructions. And this is the way I hooked it up, and it works perfectly.

here are my settings by the way: w/6psi spring wastegate
SET Boost = 23% = 10psi
GAIN = 20% (have not played with this too much)
START boost = 7.5psi (misleading, but it really mean start wastegate bleeding at this psi)
