Appreciate the thoughts.

"MAF? (Maybe a Pro-M, but a 70mm MAF is still bigger than the TB)"

Aussie, the stock MAF meter sucks. It is advertised as 70mm but when you subtract the 12mm center post it is about 58mm. The center post is flat and I suspect makes significant turbulence. I have an SVT 60mm t. body optimized by Brad Noon and adding the Pro-M meter + open K&N to this smaller t.body was worth 12 HP at the dyno. I think with a 65mm t.body, a bigger MAF meter will be a must.
