So I have a DOS CAI installed and love it! However sometimes lately when I take my foot off the gas and I hear (what I think is) the turbo pressure releasing I hear sputtering. Seems to happen after a hard accelleration. I put the CAI on when the MCS was less than a week old and I've got 20k on it now. I noticed the sound within the last few k. Any ideas?

thanks!

I believe what you are hearing is the compressed air hitting the back(exit) side of the turbo impeller after you let off the throttle. You hear it because you have an aftermarket cai. My current vehicle, Dodge SRT-4, does the same thing.
