Hey guys my friend gave me the sct tuner 3015 SF3 to use but I'm not sure if its compatible with my Focus or not. Has anyone ever used this model before on our cars?? I know its $150 to unlock but haven't figured out if its married or not. If that's the case it won't be worth keeping for me if I'm putting out almost $500 for an unlock, custom tunes and a wideband. The model number starts with X3. Any expertise is much appreciated.
