I think the WOT stuff could be sorted with the SAFC... Not perfect but close enough... You can go +/- 50% all through the rev range...
I'd be a bit worried about the idle and cruise though with a big cam... Same amount of adjustment, but I'm not sure how the SAFC would handle the varying airflow at idle...
Couldn't hurt to try though... FWIW, the SAFCII would probably do a better job due to extra mapping points... But why not just get an older Microtech? About the same price as a SAFC these days...
