2010 turbo engine. Stage 2. No other engine mods. No changes in 30,000 mi. 62,000 miles total.
Driving along today, all of a sudden I hear a medium roar at moderate acceleration. Expressway cruising almost normally quiet. This went on for 5 miles or so while I kept testing to listen and determine the location. It was definitely coming from the engine area or as far back as midway. Then as fast as it started, it stopped!!!!!! I just know it's going to do it again.
Ideas please....
