Sorry about the voicemail but we are closed on weekends.
We discontinued the I-2 programmer 5 years ago (maybe longer) so it's no longer something we support. The I-2 does have the ability to tune multiple vehicles but it can only do one at a time. So, this means that your buddies truck would need to be returned back to the original stock program and then you would be able to use it on a different vehicle. You cannot have two vehicles tuned at the same time.
