I'd like to know too, with and without vacuum connected, I am going to get an AFPR very very soon, as my stock one is leaking from the seam itself.

I believe stock is 38. I run mine at 32 with vacuum off. But, thats to compensate for these 30 lb injectors.

38-40 with out vacume is stock if your heads are ported and you have a cam you may need a bit more. I would start 38-40 listen for ping if no ping you should be ok.
