Thanks a lot but what about the SAFC or whatever it is whats it do and is it really worth the money for the gains or is turbo better?
no the SAFC is not that great...it is an air/fuel controller that tells the ECU to do what you set it up...but then the ECU will just reset itself and go back to normal settings. It is not worth it. There are no gains with the SAFC.
You could not compare a turbo with the SAFC.
