You should be able to run 310's with no AFC or AFPR.
I can tune 440's with an AFC alone, though it is not necessarily the BEST way to go about it. However, my long AND short term fuel trims are close to 0 at idle.

check the turbo sect though. i asked a similar question about running 30lb'rs before installing the sfmu, but i do not have an safc. anyway, from the people that have done it, it seemed like it would run, but very rich and probably eventually kill the o2 sensor.

30lb injectors with no SAFC, and a regular FMU with the 8:1 disk will "technically" work..the car will start, run, and drive...but it will be VERY rich. i know this from experience. it will smoke black pretty badly in boost(least the car we tried it on did). runs kinda rough part throttle driving also. www.TeamKLR.com 1997 Silver RS 12.3@118mph,20psi, race gas(drag radials) Wiseco 10.5 Pistons Eagle Rods T3/T4 Turbo Custom FMIC Greddy Exhaust 440's

Except this isn't for a turbo app, where some form of fuel pressure regulator is included.
On stock fuel pressure regulator, will it work? Or does an adjustable pressure regulator need to be installed? Will the S-AFC allow the stock pressure and ECU to hold it.
