Originally posted by 740 turbo brick I had turbo flutter on my Volvo and it was because the BOV wasnt opening enough or at all. The fluttering you hear is the pressure waves from a sudden throttle close bouncing off the impeller. Eventually can cause turbo damage depending on how severe/boost levels. Not sure on your cash situation but a Megasquirt ECU will be your friend in the 420A world. Best mod, turbo or non, hands down. If you dont got the dough for that, at the very least get an SAFC. Those wont help as much as MS, but its better than nothing.
Safc isn't going to help tune in boost, kinda pointless with stock injectors. But yeah the flutter could be compressor surge, where do you have the vac line for your bov sourced from?
Oh and you said you have a wideband hooked up, what kind of readings are you getting under boost? And are these issues in boost at part throttle or full throttle?
I contributed to the Wiki! EVO IX - just a really expensive boost gauge and a K&N air filter 96 Eclipse RS -awaiting registration and inspection 95 Eclipse GS - parts car Mods/Profile - http://www.2gnt.com/index.php?d=cs82685
