SCT had their great tuner giveaway last month and due to the fact I never win anything I entered my wife and myself. Now something happened in the cosmos and certain stars must have aligned because not only my wife won but so did I! My first question is will the SCT X4 canned tunes improve anything on a completely 100% stock 2010 6.2 Raptor? Secondly what the hell do I do with the second one? I don't think I will be using the tune if there is no improvement with out upgrading but would maybe use it for the OBD reader.
