[BrownieHeavyHauling136]

Ok so I want to try vivians tunes seems the general consesus is they might be better. Im happy just not estatic with my Id Tunes (Tow, Dfuser Race, Extrem Race) ****s a little rough too. Now my question I have a Xcal 2 Tuner from sct not a 3. I dont wanna lose my three tunes now can I save them and put them back on the tuner if I want. Thanks

Did you buy the X2 used with the tunes already on it?

Tunes are typically emailed to your computer then loaded on the SCT device. You keep all your tune files on the PC. You can have 3 tunes on your X2 at one time. If you bought the X2 with tunes already on it they can not be transfered back to the PC.
