These are obsolete, but solid for an '08 and prior truck. Will not work on a '09+ PCM.
Now you will have to find a custom tuning shop to buy tunes for yer specific truck. You will need the strategy code in yer PCM ( pulled via the device), and the serial number on the back of the X2 ( or on the Device Info screen ). The tuning on the device, if any, will not work on yer vehicle - and there are no canned tunes on an X2.
You do NOT need to send the unit to anyone for retuning - you get the files emailed and you load them yerself.
You can use ANY SCT custom tuning shop to write yer new tunes.
Expect to pay ~$70 and up fer each tune ( prices and 'bundles' vary ).
May need to update the firmware on the device using free SCT Updater software.
Lastly - confirm the device is not VIN-locked otherwise it will cost you ~$150 to unlock it.
EDIT - ah, I see good ol' Franchi is on the case! Thankee, sir!
