2012 silverado diablo i3 93 tune

[Jeffrolv1]

I'm curious to know if I can use a 93 octane tune while using e 85. My truck currently has a 91 tune and I'm noticing a slight lag from a dead stop. It's only happening in the heat of the day in las vegas

yes you can use e85 on the Diablo Tune... but only if your truck is a factory flex-fuel vehicle...
