Each AA tune is developed in-house using advanced ECU calibration techniques and real-world testing.

These custom tunes are available in multiple levels, from mild performance upgrades on pump gas to extreme horsepower gains for race or E85 setups.
Choose from six distinct tuning levels to match your riding style and modifications. Level 1 through 4 options are ideal for stock injectors, offering up to 200 RWHP with simple bolt-on upgrades. Levels 5 and 6 are designed for those running 1200cc injectors and wastegate adjustments, pushing power beyond 210 RWHP. With these tunes, you can experience explosive acceleration, higher boost pressures, and smoother power delivery across all RPM ranges.
