Your factory warranty will be void upon loading a tune from any aftermarket company and Alphaspeed is no exception.


Pay close attention to pricing info. Prices may change depending on options chosen for your configuration.


Please note that all sales are final for all tuning services and/or ECUs provided by Alphaspeed Midwest. A $100 non-refundable deposit is required to create and hold your appointment if being tuned in person. Full payment is required prior to any ECU tune or modification. Professional removal/installation of your ECU is recommended. Working with your vehicle's wiring and powertrain/drivetrain management system requires specialized training and experience. Alphaspeed Midwest is not responsible for damages incurred to your ECU, vehicle, or vehicle components due to inappropriate installation.


*These numbers are estimates assuming a healthy engine, full bolt-on engine modifications, appropriate temperature and humidity settings, and may be dependent on fuel type.

Genesis Coupe "GO" Tune

  • GO style tunes are the best bang-for-the-buck way to add power to your Genesis Coupe.


    For some Genesis Coupes, this is a mail-in option also. So you may not need to visit a physical dealer.  Simply remove your ECU, ship to my location (I pay shipping both ways), then have your ECU reinstalled when it returns. Your engine configuration (2.0 or 3.8) determines what is modified in your flash. All GO tunes are configured for use with 91/93 octane fuel only. E85 is not an option for a GO tune. E85 is CUSTOM tune only.


    Note - a SHOW tune is NOT a required base for a GO tune
