I took out my 720cc injectors and put in some that are supposed to be 1000cc. The a/f was then very lean across the board, near idle as well as under boost. So I had to turn the fuel settings UP for the new injectors. I'm using an AEM EMS to tune and FJO wideband to monitor a/f. I took out the plugs to verify the color agreed with what the FJO was telling me, and it did. I'm basically maxing out the 1000cc injectors at only 26psi with a small turbo (t60). I think my base fuel pressure is set to only 30 psi (normally I would know for sure, but my stupid gauge or sensor died). I was told 30 is too low and I may need to increase it to 45 psi. Is it normal for a/f to go lean like this if the fuel pressure is not increased, or do you think they sent me the wrong injectors?
