when i am seeing the 11400 is when the engine has built the most boost, right before a shift, so around 10-11psi.

Checking my notes my scan gauge gave these readings. Not sure how this translates in to your nubmers.

With a 3.4" pulley .67 PPM
With a 3.3" pulley .90 PPM

These readings are at idle and come from the aeroforce scangauge

OK, I was looking at the wrong readings. You want MAF frequency, I don't have any notes on this with my 3.4" but with my 3.3" I'm getting about 2400 with the engine up to operation temp and idle about 900
