The safc works extremely well for idle, part-throttle, and wot adjustments. You need the ecutek to help with tuning as well as a wideband or egt gauge. On stock injectors you can maybe add about 10hp but the stock ecu can be fickle so it is easy to hurt hp as well if you do not tune carefully.

I think the safc is really not needed unless you go to a larger turbo and larger injectors and/or fuel pump.

Good luck,
