Thank you for looking into our Stage 1 And Stage 2 E30 WRX Tuning.


We have been working on the FA20 Since its Debut in the Subaru world in the BRZ/FRS years, it was evident then that the FA loved E, and once we got our hands on the WRX VA with the FA20 it was the same story.  Simply adding E30 and the proper tuning transforms the WRX into what it should of been from the factory,  it immediately feels like a new car and the power reposnse is imporved greatly,  on pump gas 91/93 this WRX starts to feel slugish as you near redline. Swapping to E30 removes this and actually increases power all the way to your new rev limit of 7,000 RPM.




Stage 1


E30 Fuel Mixture

  • 290-325 WHP
  • 290-350 WTQ




E30 Fuel Mixture

  • 330-360 WHP
  • 320-360 WTQ



    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 meaning you can run E30 on the stock intank pump if stage 1, and its suggested to upgrade the in-tank fuel pump if going stage 2 E30.
