I'm about 320 at the flywheel, you're probably less than that so you need to pull yours down even further - maybe 32? Check the analyzer on this site, plug in your numbers and you'll get an idea where to set it.

Wow you gained 35 hp from that?? My stock regulator is at 38 w/out vac, but I keep getting an 02 lean code, but "only" when I'm cruising at 70+mph in 5th for awhile. No other time whatsoever. And that started after I put on my homeade cold air. My stock 70mm MAF is also postless, which would further lean it out a bit. I do need an adjustable FPR, and my timing is 14. I'm weary of bumping it more when it's doing what it is right now. Did you have yours dynoed? If so then I should have a bit more than that, and I know it has more than a 104.7 with my current combo.
