Just started having this issue.. Car boosted fine a couple months ago, held strong at 16-18 lbs. It was garaged and when I got it back out to drive it this was happening. The hissing sound you hear is NOT a blow off valve. This car does not have blow off valves. I am still using the stock recirc system. Mechanic said it could be a loose hose popping off at high boost but after inspection of the hoses I could access I saw no splits or loose hoses. Any info of someone with this same problem is appreciated. I am running a Greddy Profec B II, and no matter what I do to the settings this issue is always present. Sorry about the strange aspect, I haven't gotten the iphone video thing down yet.

Profile contains a mostly up to date list of whats in the car. I do have t28 cartridges in my bored out stock turbo housings, not sure if I put that in the profile yet.

Again, the car was boosting just fine a couple months ago.
