I ordered some 440's and Im going to be boostin 16-17psi on a s16g and was wondering what my idle and static fuel pressure should be at? Also what pressure should I be at a wot? Is it harder to pass emessions with larger injectors? Oh and my management is a sfmu

idle pressure is going to be in the teens
WOT pressure depends on what rate you use
12:1 4:1 etc
you can search all day long for what other people are using(and you should) and that will give you a decent start but the only way to get it set for your car is to have something like a pocketlogger so you can monitor stuff like fuel trims
you need to turn your pressure at idle down enough so that your short term fuel trim is as close to zero as possible and hope that your injectors spray enough fuel at that low of pressure to idle correctly

I do have a pocketlogger so when my car is idleing my short fuel trim should be at zero? Is there something for me to refer to to understand the short and long term fuel trims? My goal is just to run 17psi daily
