Hi Guys I'm new to the Xr6 turbo Scene and I've just purchased an 03 ba xrt and I was driving home last night when I lost around 4psi of boost (Boost Gauge Reading) and a sound that's probably best described as a whooshing..... the car's got a warranty on it so I dont wanna start playing around with the piping on it.... Does anyone have any idea as to what it could be?
