You can blend up to E30 on anyone’s tune…you don’t need a specific tune for it.
For a higher ethanol percentage they offer a specific E30 tune which they highly highly recommend only using if you plan on upgrading the intercooler. However as of recently they now have 2 versions to this e30 tune - 1 for those with an intercooler upgrade and 1 for those without an intercooler upgrade. Which has sparked my interest because I don’t plan on upgrading my intercooler but am excited at picking up some extra power.
I don’t know all the science (boost, timing, etc.) behind the e30 vs the AO tune but per their website they claim superior numbers utilizing their e30 tune especially with the upgraded intercooler.
