I feel the SCT is the best flash tuner for a few reasons , it wont change your stock factory strategy to what the tuner wants , it datalogs , the new SCT cloud tuning is in beta test where you can down load your tune directly to the flasher vs downloading it to your PC then to the flasher
I also feel I have the best tune files for the MK3 Focus and you get a full custom tune vs canned tuning
