i have a mk6 gti, tuned, thought i had a boost leak cause i started to hear a weird whooshing type noise, lost about 4 psi. (was pushing 20.5 psi) now getting about 16. but no check engine light. and the turbo sounds normal till its under extreme load. ie pedal to the floor lol. could that be the diverter valve? no loss in fuel economy or anything else. car drives normal. **DSG automatic** ive tried to get under the car to see if i can access the turbo to check the DV, and i was going to build a custom boost leak tester. was wondering if anyone has experienced the same problems? really dont wanna take it back into the shop ):
