SCT and Bama Performance have released their latest handheld tuner–the SF4 and X4. We’ve laid out the new tuner’s features and compared it against the previous version.
The SF3 tuner was a mainstay for SCT and the Mustang community for many years. It was a great way to upload custom tunes received via email, directly from your computer to your Mustang, without paying the high costs associated with a shop’s dyno tune. The SF3 and Bama Performance also gave users the flexibility to change their tune each time they added or changed a modification by emailing Bama and requesting a new set of custom tunes, specific to any new or changed modifications.

SF4 vs X4: What’s the Difference?
The SF4 and X4 both share the same exact functionality and look as one another, the difference between the two being the X4 carries Bama Performance’s custom tunes backed with their Free Tunes For Life guarantee, whereas SCT’s SF4 comes pre-loaded with general purpose tunes from SCT. Bama’s custom tunes give you fine-tuned performance that perfectly sync your engine and transmission for maximum efficiency and power gains. When you go with one of Bama’s X4 tuners, you also get entered into the Free Tunes For Life program, something only offered with the X4 tuner. If you have a modified Mustang or are planning to mod your car, the X4 is your ideal choice.
