I would really like to have the AIT input in my tuning so I don't have to worry about changing temps and elevations. Here is Idaho we see a lot of both 
So I thought that getting my VEC2 upgraded by Roe would add that ability. I talked to one of the sales guys there and he said there would be no benefit on my GTS and that the upgrade was only good for gen4 and Rams. He also thought that the AIT input would not work on a gen2 anyway.
So in order to get the AIT function I have to upgrade to a VEC3?
