Update, past year's experiences with the Turbo/Built S2K
AEM FPR should be 1:1 ratio regulator meaning every pound of boost you make you gain 1 psi of fuel pressure on top of the static fuel pressure. Say if you are idling with 45 psi of fuel pressure and you end up making 15 pound of boost, your end fuel pressure should be 45 + 15 = 60psi of fuel pressure. However, I have a SX fuel pressure regulator and it is also 1:1. I set my idle pressure at 45 psi and runs 16 pound of boost. I checked my greddy fuel pressure warning gauge and it reads around 70 psi of pressure by the time I ran 16 pound of boost. That means on top of what suppose to be a 45+ 16 = 61 psi of fuel pressure, I gain an extra 9 psi more. You can call AEM and they will tell you the same thing that 1:1 ratio is pretty common on all aftermarket fuel pressure regulator.
Yes, but I prefer to set my static fuel pressure by not pulling off the vacuam hose. It's just preference. I'm just saying the increased fuel pressure after boost is normal but it must be consistant run after run.

I've already broken one ring and pinion, so I went with the Comptech differential upgrade and a Kaaz differential, although technically, I haven't addressed the situation with the ring and pinion. It's a time bomb. At some point I'd like to cryo treat the ring and pinion (this is probably priority number one).
