N54 wastegate rattle
So I had my car tuned on a Cobb stage 2 tune for a night. That same night I went on a cruise with my friend and when I drove the car for a couple miles I can hear the car had some what of a exhaust leak and with out thinking too much about it I did a pull in the car and the car put me in limp mode so I just drove the car home and notice I had wastegate rattle so I let the car sit over night and the next day same issue so I decided to untune the car and as soon as I untuned I drove the car and I didn't hear my bov at all after putting a couple miles on the car it was like nothing happened no code and I was doing constant pull to see if the problem would come back and it never did, after that I decided to retune again and as soon as I finished flashing I turned the car on and I heard the same exhaust leak and wastegate rattle so finally I left it untuned. If anyone has had this issue let me know idk if my turbos are going bad because when it's not tuned it drives normal also I checked the boost canisters and they seemed good anything would help thank you
