    Kind of like the title says. New '18 GT Premium Convertible A10. Did a baseline dyno and 2 weeks later dyno'd with an E85 tune as the only mod getting 40 more ponies to the rear wheels. Seems like a big gain to me. Does this sound about right? Less than 1k miles on the baseline and just over 2k miles on the E85 run. The only other mod I have laying around the garage are a set of Pypes off-road long tubes. Dreading trying to install them though. Lol...

    We saw the same gains on my dyno after E85.

    And that confirms it for you!
    I would say that that is about right. Shaun, would a car with more mods see more gains?

    Yep sounds about right. Unbelieveable what these things pick up from just a fuel change and tuning

    Waiting on my E85 tuning right now. The 93P was an improvement.

    No it comes down to how much ignition timing we can run on pump vs E85. There can be a 10 degree difference pretty easily due to the 12:1 compression.
