Is it ok to drop fuel pressure to lean out? My tuner set my boosted engine up rather rich all across the board. 11.2 a/f cruising and generally richer under boost down to 10.7. I run a wide band and can monitor the a/f. Can I drop the 60 psi down to 55/50/45 to get the desired a/f ratio that I want or is that not going to work.
If yes, say that I drop the pressure 5 psi, would that evenly lean out the a/f across all rpm's?
What is the least working psi (generally) for injectors to spray correct

Your not going to see anything noticable with a drop that low, I'd go 5 psi at a time.
A better idea though would be to have your tunner set it up right. You paid for it, get what you paid for.

Well it's a great ture, very similar a/f all over, just on the safer/rich side. This is an off road car and dosn't fit the dyno well. I just wanted to know if dropping a few psi was even an option.
