Gonna finally due my power-adder project this year with a tune and debating the E85 option. I'm in the north suburbs but it's not a DD and I usually head northward for rural road trips. SW quad driftless area, northwoods up to UP. Of course once you get 25 miles past the border you're in 91...

Or you could just get the one's Ford copied like I did.
