CAMARO6 - View Single Post - Does Ethanol allow for more boost or less boost??

I’ve been doing a lot of reading and I hear that Ethanol can increase the amount of boost you can run due to keeping the engine cooler but also less boost because fuel systems can’t keep up with it. I’m just super confused on what it depends on? When is it more beneficial to run 93 vs E85 and vice versa?

Is there a point where the boost on 93 would out-way the benefits of Ethanol?
