I got mine a few weeks ago and it was a pretty good buy. Got my mpg higher coz of the Performance tune. I got a new mod on my car recently so I ordered new tunes from Bama, they emailed me the new tunes and how to upload em on your device. Followed the procedure but when I open the SCT Device Updater, it can't detect my X4. It just says "Can't find device". Not really sure what's wrong.
