cool, thanks. after re-re-re-re-reading this thread, i did come across some references to that. i honestly am finally beginning to grasp the how's and why's of how this mod works. this is my first turbo car and i have a pretty sophomoric understanding how the turbo system works in general.
this fluttery business still weirds me out and is pretty bad at low to mid boost shifts or throttle lifts. i noticed seeeeya's comment:

The light compressor surge I initially got with a quick throttle lift has largely disappeared after tuning my WGDC, AND learning to drive without snapping the throttle shut
while i still have yet to log anything since the mod, i feel too green to dare start tweaking with my tune myself, but i also think my driving habits are also coming into play too, in terms of trying to not "snap the throttle shut." though sometimes even rolling off the throttle is giving me flutter.
AND i still have that weird squeaky noise, which was the entire reason i did this mod. others with my same noise said the stock bpv was the culprit and went away with an aftermarket one. i just want to get these issues resolved before installing my DP and etc.
