safc question
i have an safc and an air fuel ratio gauge...i know that it is best to tune the safc on a dyno, but i dont have the money for that. for now, what is the best i can do to tune it for maximum performance? do i need it to run slightly rich throughout the rpm range? highly rich? close to rich but still in stoich? help me out guys.

Simple -- DON'T. If you can't afford dyno tuning, don't touch it until you can, and don't change your boost until you can.
If you do, you'll regret it.
Oh and buy an EGT gauge to MONITOR, but NOT TO TUNE.

Never use an a/f guage to tune. Leave it as is untill you have money to get it on a dynoe and tune with some form of a wide band. Your A/f guage is using the signal from a narrow band O2 sensor which comes stock on FC's so it is not reading accuratly enough to do muc good at all. those things are just for a light show.

If your car is stock, you will see some gains by leaning by about 5%-7% from 4000 RPM up. But that is the only change you should make. You really need a wideband to do proper tuning.
This is NA only.

Can't afford dyno time? Aren't they somewhere around $40-50 p/hour in the continental US? You can also tap into your O2 sensor and do a base tune that way or use default settings (0).
