The Performance Tune for your truck is for 91+ octane only and nothing less. I ONLY run 93 octane in my truck and nothing less with the Performance Tune. After you run a couple of tanks of 91+ you need to go ahead and get your ltfts dialed in. Just follow the link below and it will explain everything. If you need any other help just post up. With this tool you are capable of squeezing a lot out of your truck, it is just up to you to take that jump and do it. There are quite a few of us that are here to help in any way we can.

your risk serious detonation when running a lower octane fuel, which means you can hurt your engine.

Spend the extra and get the better gas. It costs about 2 bucks more per tank. Once you get everything dialed in, you'll still be saving money because of the increase in MPG.
