Default Fuel grades in your truck
What grade gas do you use and why? Tuning, FI, or just because.

Supreme for me .... the blower on top and agressive timning pretty much have to have it.

I ran 93 ever since I got my truck. I ran a tank of 89 in there to see if there was a difference and OMG did it feel like a pig running around town. It took 2 fill ups of 93 to get it running back like it was before the one tank of 93.
