hi guys, wonder if you can help me - my 9k aero is driving me mad.

It DEVELOPED what i describe as turbo flutter while running stage 3.

The condition would happen at around 3250rpm at full boost (1.35 bar at the time) it clears as the revs rise and can happen on part or full throttle but not on lift off.

I recently changed up to a 19T and the problem is soo bad now.

As soon as I hit 1 bar at 3000rpm the fluttering starts and is really bad.

So trying to establish why my hardward wont take low boost levels and is causing surge.

Any suggestions would be appreciated.

thanks
