What Base FP and FMU disc for 370's and a32 maf

Looks like I am an idiot and did not order the connector to plug in the z32 maf that i have sitting in my garage right now, but I still want to install the injectors either tonite or tomorrow. I was looking at installing it with either the 3.33 pulley first and testing them out or going straight to the 2.87 pulley (i am leaning towards the 3.33)

I read the threads in the stickies and saw that eric j set his base fp to 22 psi and jaime used the 3:1 disc. I was looking at my fmu discs last night (i have 4, 6, 8, 10 and 12:1 discs) and the smallest one doesn't have the ring that i need to place it on.

So I guess my questions are....

What should my base fp be?

What FMU disc should I use?

What FP should I be seeing at wot (8-9 psi on the 3.33)?

that is a smiliar setup to what I am running, but I am running the 3.125 pulley with 370's. My base FP is set ~24 psi, and WOT is low 40's. I have a 4:1 fmu disc, and I have not been able to get a very good tune yet. I have a 3:1 FMU disc that I got from vortech about a month ago, but it is just sitting in my room until I can get back to the dyno. I tune with a SAFC-II and with the 4:1 disc my car is crazy rich (you can see it in the boosted dyno section). I am on a A32 MAF and stock A32 ecu. Hope this helps some.
