can you change tunes ( like have lets say 3 tunes ) ( racing , city , Factory)
can you change it yourself? like if something happens u change the tune to factory so they cant tell u tune?

You send Trifecta your info.. so what kinda setup you have.. they calibrate it for you, send you a device, you upload it and they keep your original setup as a backup for warranty purposes. After you install your tune, you send the device back.
