Running lean!

Running lean!
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.

When I switched to 850cc primaries, there was another setting that I had to change as well as the injector size. I don't remember exactly, but I think it was the duty cycle. You might want to try increasing that. It was on the same page as the injector size setting with the datalogit.
Also try posting in the PowerFC section.

You are trying to tune by changing the reported injector sizes? That is going to change fuel delivery everywhere, which is not what you want. Even with the Commander you can adjust fuel on a cell by cell basis.
How are you measuring AFRs and where is it running rich?
