Well, I got out of my car to stop by the shop to say "Hi" and stayed for about 10 minutes. I got back in my car, started it up and everything was fine. While driving down the freeway I noticed my BOV wasn't making the same "WOOOOOSH!" noise like it was doing before I turned it off, but now it makes a fluttering. IDK how it happened but it sounds sort of like the BOV's that sound like rattle snakes. I have the TurboXS BOV that came with the CN1 kit and I didn't at all touch anything after I turned off the car, I kept it on for a bout a minute or two to let the turbo cool but that's all. So now I'm wondering if there's anything I can do? I checked the piping and the vacuum hose and they all seem to be on tight, so now I'm stumped .
