i only switched to 91 because the pinging was terrible on 87 and 89. if you don't have a problem running 87, stick with it.

Basically the performance tune is advancing the timing. Too advanced and the truck will ping which is what the 91 octane is for.

Well the 87 octane mode on my tuner works great and got rid of my death flash....I just wanted to know if anybody uses the 91 octane mode and how much better it is....
