Recently got the i2 for Christmas and now I'm having issues with either it or my truck. Loaded all of the updates from my computer before even attempting to plug it in and now every time I try to do any type of tune it says something along the lines of " one of the ECU's in this vehicle has already been tuned with a diablo product. Please restore it to stock condition and try anew".
Any help would be appreciated.

no issue, its just telling that the vehicle already has one of our tunes.
Post the files here that you have in the tunes folder on the i2 drive and let me know what vehicle it is please.
