Anyone running a Holley Sniper 2300 on their slant?

If you're thinking of adding a turbo, I would recommend multiport EFI over a TBI. TBIs have enough fuel distributution issues on NA engines as it is. While you can make it work there's a reason there were only two OE TBI turbo applications I'm aware of (Mitsubishi Starion and Colt Turbo, if you were wondering) and a bazillion OE turbo multiport combos.
