Well, i feel dumb, because the problem actually is the wastegate.
I don't know why, but it holds positive pressure great, but i figured out with the vacuum pump that it won't hold ANY vacuum, at all.... and since the BPV and WGA were on the same line from the manifold, the BPV wasn't getting enough vac to open, hence the compressor surge.
When i had to replace the wga before, i ordered it from atpturbo or something... there are more options out there now aren't there?? Does anyone know if any of them will last more than 25,000 miles???
