Deposit payments can be made HERE to start your appointment process if opting for an in-person tune. Full payment is required prior to any ECU tune or modification. Professional removal/installation of your ECU is recommended if you plan to mail in your ECU or are purchasing a spare: working with your vehicle's wiring and powertrain/drivetrain management system requires specialized training and experience.

Hyundai Genesis Sedan Tune
An ECU tune is a cost effective way to safely add some flair to your current setup while still maintaning stock-like drivability and fuel economy.
Simply remove your ECU, ship to my location, then have your ECU reinstalled when it returns. Your engine configuration (3.8, 4.6, or 5.0) determines what is modified in your tune. All SHOW tunes are configured for use with 87-93 octane fuel. All GO tunes must use 91/93 octane. All Custom tunes must use 91/93 octane or E85 (determined at the time of your tune).
