Yes I'm going to tune for windshield washer fluid since it's a lot easier to get ahold of than this other stuff that Snow Performance sells, aside from being a lot cheaper. That way I can throw in the 49/51 mix and it should still work without any trouble and pick up more power. I got a guy that tunes the Mallet corvettes who will be working on my car this time....as soon as i get my car back.
