Title: Buffeting/fluttering under acceleration
Post by: 18Edition30 on August 11, 2013, 08:08:30 pm
Ever since I've had the stage 1, under acceleration there's a flutter coming from the VWracing intake, seems to drive very well, just this strange noise? Like a buffeting/fluttering under acceleration, normal or full throttle.

Changed the DV to a G revision before the map as well.

So is this normal intake noise?

I know it flutters and chatters when you let off throttle but this noise is when accelerating if that's clear.

Mine did this when I was on an earlier version on the stage 3 map. It's still does but only on the rare occasion now. I feel like its making less boost when it happens too.

Do you know where the noise comes from? Not sure if its diverter valve or turbo or both...

tbh i thought it was the induction kit. rather than non stop sucking noise its sort of fluttered on/off ?

Yes same as mine, I think it's the intake.

It never made the noise standard it just started making it since the map.

It's asif it feels a little but hesitant/sluggish when it does it.

Totally normal. It's just resonant noise from the compressor wheel through your intake.
