if your getting the ecu chipped with a map from the dyno tuning the safc is useless. the safc is to let you tune the motor without chipping it. for a turbo setup I would not reccommend the safc hack, it just fools the ecu into thinking it has certain signals, you can do more damage and no good going this route. get it dyno tuned and chipped, save the money for the safc to spend on something else.
