It was recommended that i post here so..
I just rebuilt my engine and put in a primary fuel rail with 750cc injectors. My old fuel set up was 1600-850. I have the PFC. So i changed the injectors on the computer to 750's to see if it would richen up. It didn't. I was wondering if i should maybe drop it to 650 or 550 in the computer?
If Anyone who knows the PFC could chime in it would be greatly appreciated.
Yes i do know that the car will have to be re-tunned but i need advice for until then.

 

DOH? 750s would run leaner than 850s do to less fuel flow for the same injector pulse width.
