    We have been working on the FA20 Since its Debut in the Subaru world.

    One thing NO one will argue, The FA20 LOVES some good ole Ethanol. 


    Reasons you need to buy this tune:

    You're having knock issues with current fuel and want a safe more powerful tune.

    You want more power

    You want to pay less at the pump

    Want 30-50+ HP Over 93/91 Octane?



    It takes roughly 4.5 Gallons of TESTED E85 blended with 91/93 for the rest to make E30.


    We chose E30 blend's as it's a safe ethanol blend to achieve the HUGE power gains we see while staying within the safe limits of the OEM fuel system.
