hi guys, i have heard when you run more than 10 psi the stock ecu richens fuel and retards timing, i noticed this as a major flat spot on my gtst between 4500rpm to 5500 rpm. alot of people say a s-afc will cure this flat spot. I was just wondering if i ran the s-afc would the stock ecu still over retard the timing, isthe timing problem going to be that noticeable/much of an issue to be worth doing something about ie. itc?? considering my r33 is pretty stock just pod filter, turbo back 3" exaust, plugs gapped .75 and i wanna run10-12psi Any info would be greatly apreciated thanks:burnout:

ITC's suck. If your going to by both an SAFC and an ITC then you may aswell buy proper management instead:D
