hello, so i bought a car that had a flutter turbo noise, it had a spacer on the dv so i took that out but still makes the noise, it came with a cts intake, the seller told me its from that but i thought u had to add a blow off valve or something to get the flutter pigeon noise, so is there a blow off somwhere around the turbo?> i found the dv is in front of the motor so super easy to get at.. since i took off the spacer it isnt as loud but still there. any one have ideas?
