Thanks for the answers. Yep, I'm in East Mesa, near Signal Butte & Southern. Am definitely up for some offroad expeditions. Particularly interested in off pavement routes to Show Low where I have a "getaway", in the event that highways were for "some reason" ever closed.

I'm not a mechanical engineer, but would think that enhanced breathing would make engine more powerful without increasing gas consumption. Perhaps I'm wrong, and it's not too different from s/c?

That deckplate is new to me. Read the link, and I'm still a little fuzzy. Am I correct that it is basically CAI, or is it different?
