| My Car makes a quick Moaning noise from behind me (somewhere) when i Boost and Get at or above 4-5k,..and then goes away. I use to think it was the exhaust but that was changed and Sound is still there?? Crazy? Anyone else have or heard this. Im Use to and Know that pumps whine...but this last for just a few sec's at around that rpm and Goes away. Think its on the way out?Or maybe its the switch over point when it switches voltage or something? (car is 1990TT w/103k)
