So I was just getting back from a 12 hour drive, where I was a mile from home, and I lost about 30 - 50 % power, I was cruising at about 75MPH in fifth gear when I just dropped to 55 - 60 MPH and could regain my speed. I couldn't hear the turbo charger and when I got in my driveway I could hear that the engine noise or the exhaust (whichever, i dont know) sounded really muffled. And thats my dilemma. Any help would be greatly appreciated
