Did your turbo sound get louder as well as your BOV when doing the CAI? I know my last turbo car got significantly louder just from a CAI. Do you have pictures of it?I just just custom fab a CAI , with some 2.5" tubing and some couplings as well. As for a Turbo noise if its too quite.. just find a place to install a Blow off Valve , then you get the Turbo purge you guys want!
As anyone noticed that the turbo's are awfully quiet. Anyone tried a cold air intake or anything to see if we could get a little more sound?
I just had to have the boost control module replaced and now the turbo is difficult to hear.I've got the N. Amercian made car and can't hear the turbo.
I do hear engine knock under light acceleration...on dealer first tank of gas.
