What would make the most power is the simple question, lets say both ST's have the exact same mods, stage 3, E30 vs a 93/100+ mixture like turbo blue or something like that. Around where i live i can only get 110 octane turbo blue from a valero about 30 miles away from an actual pump. So for ****s n gigs lets say E30 (3 gallons of E30 and rest 93 full tank) vs 3 gallons of 110 and rest 93? anyone even done a high octane tune? i know the E30 is way more popular because of ease of it at the pump, and the availability of 110 isnt a regular thing, on top of the $8 a gallon price tag.

Chemically speaking gasoline will always have the potential to release more energy than ethanol. Ethanol has an octane of 109 so compression to generate more power is somewhat null in your case. Given that modern motors are designed to use gasoline and not ethanol it will always be more efficient with gas, but thats generally only a 30% difference when running E85. It would be less with a E30 blend and probably negligible to most people. All in all in think you would have to play with the tuning and see. You should be able to get more out of the turbo blue mix but how much depends on a number of factors and i think would be very small and likely not worth it considering the price and availability of E85.

You would want to add e85 to your 93 to make e30.
