Tony-
I have SS short slashes, open pods (Freak-like) and also am below 1000 ft. I run 150 mains with 45 pilots. I'm at about 2.5 turns out on the mix. Also drilled the vacuum ports, but I think your year are already wide enough. Runs like a bat outta *^%$ with almost no decel popping. I'm a happy guy.
