As far as the PFC Idle issue is concerned.
Advance the timing in the commander to 17-20adv around idle.
Legnthen the IACV Hose, then adjust the IACV nut in between runners 2 and 3 to correct the airflow.
Redrilled injectors flowing alot more fuel all time time, time time? lol.
High Impedance Injectors are high impedance injectors. Total cylinder/fuel volume is dynamic not static. 740cc's should be ok for idle using a style 1 injector. But they are high impedance, they are crap, crap solenoids, the lowest you will "actually' get is going to be 1.5ms.
Style 2 (SARD) is like cheating, they are so cool, way better nozzles, tighter wrap on the solenoids, giving them a great lag/response time.
In short.
You Lag time is the EXACT same as the series injector you are using, if the injector body/solenoid was originally a 370cc injector, the lag time will remain the same because they have only enlarged the pintile tip, not replaced the internal solenoid, to some "majic one".
To further correct your idle. You are probably not going to ever idle at stoic, why you are trying to do that, i dont know. Maybe preheat the cylinders at a stop light (ROFL).
12-13af/r at idle is pretty damn good, some like it in the 10's.
The PFC is hunting for idle correction using the map for 370cc injectors (DUH), you need the dataloggit to reprogram for that. Try turning idle correction off in the setup menu.
As stated above, the best way to keep control of your idle with the PFC is going to be legnth of IACV hose, Adjustment screw and Ignition timing.
Oh yeah, Idle fuel pressure can make small changes to your total fuel at idle if you are up against the wire (1.5ms)

No, I believe, I posted in threads you were in multiple times, explaining that the PFC was a big pain in the ass, unless you had good previous experience, or a tuner nearby. Myself, and other forum members, all referred you to multiple various tuning options.
Tuning the PFC is well documented online. You are not cracking some secret code. It is a bitch. I did not hijack your thread to push a product, now you may see, I was honest to god, trying to help you.
