    Nice. Is that the gain over the base Roush tune?

    Nice gains. Was this using 93 octane?

    People often don't realize just how much power these blower manufacturers leave on the table in their tunes. We've seen similar results as well.

    Those are impressive tune gains. How much power to the wheels did the '18 GT make with the Roush blower (supporting mods) and custom tune?
