Fuel pump ques.

[camcojb]

I finally got my new ecu up and running pretty good exept one thing, fuel pressure does not climb as much as boost. I'm seeing about 18 psi boost and fuel pressure only goes to 57-58 psi (43psi base). My afr was in the high 12's, only 16* adv. thankfully. I'm running 55lb injectors with 4 xtra 72lb injectors on secondaries.
Now I'm wondering if the a1000 is enough.

If the fuel pressure is steady I would not be concerned. I still would look at injector duty cycles also, and I'd richen it up a bit more with pump gas. Upper 12's a/f is the high limit, mine actually picked up 50 rwhp by richening it down to 12.0 or so.
