Hey, with my recent issues running the Cobb AP I think I might have become a little paranoid but have a question anyways. Is it normal/do you guys get a popping/backfire sound at WOT and shifting sometimes? (not all the time). It's also sometime accompanied with a black cloud of smoke. Sounds kinda like this...its pretty loud
