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.

93 octane around here.

 

93 octaine for me.Cause thats what i had allen tune for!

 

93 octane because my truck is programmed for it.

 

I use 89 right now, but as soon as I install all my parts I have stock piled with my 93 Nelson Tune it will be 55 to fill not 45

 

Always 93 for me.

 

87 becaqsue I am lonely and don't have a tune or a blower(so no reason to run better)

 

93 for me as that is what I had Allen tune for.

 

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.

 

nelson 93 tune always
