Yep, just listen to the engine. Mopars are not running, but that is what I do in the Cyclone. My mopar buddy and I were crusing some time ago and laughing about that. Tunes would probably just ruin everything as we were cruising down some old 2 lane country roads. I looked at him and said, My god, if I didn't know any better, this could be the 1970's. Just 2 old gray beards crusing along without a care in the world. Even funnier is when we were on the 4 lane road, folks were passing us and giving the, "Yep, that is pretty much what I expected" look.
