I was on the fence between MAP and MAF myself. I always figured MAF would be the better correlation to IPW (which, IMO, would be the best signal to use).

So I went to ScanDepot and downloaded dozens of scans (L67 supercharged and L67 / L36 turbo'd motors). I found that, in every single case, in boost (i.e., MAP>=100 kPa), IPW was far better correlated with MAP than with MAF. I don't know why, it just was.

I don't know if that helps you, but I decided a MAP-based system would be fine based on that.
