Doesn't the 1.5L take 87 octane? As in Premium fuel is only "recommended" but not required.
If so, what is the increase someone can expect on regular pump fuel, not 91, not 93.
Your ECU will pull timing which kind of defeats the point of a tune to begin with. Tbh just don't run 87 in 1.5T manuals. You bought the fun car, pay the fun car tax.Fuel Octane:
We offer a 93 octane and 91 octane version.
You may use a 93 octane tune if you plan on running 91 octane + 1.5 gallons of ethanol to increase octane.
Use of lower quality fuel may result in elevated k.con values which will increase knock retard.
