i was pulling out of my local watering hole and was about to get on it when i heard a loud pop. sounded like a hose blowing off. i was at only 1or2 lbs of boost when it happened. i let off and stepped on it again and the car was fine. pulled over checked all the hoses and evrything looked fine. drove it home later that day and no problems. 23 lbs of boost with no problems. any idea what may have made that noise. backfire through the intake?
