RE: anything on a v6 turbo???
One thing I'd check with a blower on any engine, is the spark plugs. Don't these new Challengers come with platinum plugs?
I put a blower on a 96 Ram, and learned quite a bit. In that case, I had to revert back to standard ol laying around Champions. The spark would blow out with platinums. 3500 rpms and it would bang out. Just a thought.
