Hey guys,
I got my tune files from BBP. They sent me 5 files a 87-89OctSport, a 87-89OctTune, a 91+OctSport, a 91+OctTune and the Stocktune file.

When I plug my AutoCal into the truck I have the Option to Prog these files as well as four others named Full 87-89OCtSprt, OctTune, 91+OctSprt and Tune.

Anyone one what the difference in these are??
