Well, I'm a junkie. Tuned my F-150 with the 5 Star 89 Octane Performance/Tow tune. It's amazing. It's not that it's really super fast. It's just that this truck should respond like this right from the factory. I know this is the wrong thread for the F-150, but I also ordered 87 and 90 octane tunes from Torrie at Unleashed this morning. 3.2 milliseconds later we'd exchanged a few emails and he sent me two files. I'm switching out my plugs tomorrow and then my wife's MKS will get an upgrade. I'm guessing that the rest of you tuned SHO and MKS owners absolutely love them. All this messing around with these EcoBoosts has taught me one very important lesson... I need a 2015 5.0 Mustang.
