A question for guys running the 4.6 4V motors with a blower, not just terminators, but any 400-600hp blower 4.6 modular setups. I just got done tuning and changing my base mailorder tune A/F at WOT and now I go down to 11.5 A/F right before my MAF pegs (approx 480-490 HP). I was thinking that I want to be at the rich side of the range SCT indicated for my car, when the MAF can't meter any extra air, and it moves back towards lean. I also transition to richer, sooner and that seems to help midrange spool up. So I wanted to know what everybody else's thinking is on their A/F, what they try to run and why?
