Fuel Octane:
HIGH QUALITY 93 Octane REQUIRED. Compatible with up to E15.
If you only have access to 91 octane you can use 91 Octane with 1.5 Gallons of e85 per fill up from empty. Use of lower quality fuel may result in elevated k.con values which will increase knock retard.
This tune is not compatible with a flex fuel kit. You would need our stage 2.5 flex fuel tune to run a flex fuel kit.
