Hi i decided to try dv blanking to get the flutter but i get no difference sound what so ever,now would this be because of a leak or has anyone got any ideas? cheers

 

do you have an induction kit fitted or standard airbox?

 

standard airbox mate

 

Standard airbox and A TMIC make it hard for the flutter to be heard, as you found out (so did i when i tried) ive just removed the snorkel system in the inner wing on my standard airbox to try and get some of the flutter noise, yet to test but heres hoping, if not, was worth a try lol (on a 95 WRX)

 

Should be a bit of flutter bud, my 03 WRX fluttered with just a stiffer VTA spring setting. Standard airbox and TD04 running stock boost. I did have the snorkel removed though.
