Real benefit:
Combustion motor life cycle shortened enhancing planned obsolescence for manufacturer product cycles and future sales. Diluted gas is less efficient and despite paying less you’re actually paying more both near and long term. So much winning.
Why? It raises the octane, so you can run more boost easily. It just requires more fuel delivery because it has lower energy density. Are you near injector or fuel pump flow limits?
You absolutely need a tune for e85 exclusively. You can throw a few gallons in to fix some timing issues but I’m pretty sure you need to adjust ignition timing to keep your afr in range to run it exclusively.
E85 is rarely actually e85 so an ethanol content analyzer is usually required to adjust the ecu accordingly. It’s not just higher octane, all that does is allow for higher compression at a similar temp.

Fortunately, us Americans suck at math. A consequence of our “world class” public education.
20th percentile, surely
Why would you want a 1/3 pounder when you can have 1/4 pounder
Wut?
I drive a 2018 wrx with a very modest etune. It’s tuned for longevity as it’s not even an hp gain. This will be difficult to run in my car.
