everything is fine; you should hear a "PSHH" when you let off. if it was not working correctly, you would hear a horrible fluttering sound when you let off the throttle; it is the pressurized intake tube before the throttle blade venting back through the turbo, which is still pushing air forward. My GMC Typhoon does this as it came without a BOV (blow off valve, hooter valve, etc) and it sounds horrible. It can damage a turbo after a while.
