    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.

      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?
