The Audi D5 A8 & A8L represent the pinnacle of Audi luxury and technology, powered by the advanced EA839 3.0T Turbocharged V6 engine. While the platform delivers exceptional smoothness and refinement from the factory, the stock ECU calibration leaves a significant amount of performance untapped.

As a large luxury sedan, the D5 A8 carries considerable weight and utilizes a unique engine bay layout that prioritizes packaging and comfort over true outright performance. Jackal Motorsport tuning unlocks the true potential of the EA839 platform, bringing the A8 to life with improved throttle response, stronger torque delivery, and significantly enhanced acceleration.

Our ECU calibrations are engineered specifically for the D5 platform and carefully optimize boost control, ignition timing, fueling, and torque management strategies. The result is a smoother, stronger powerband across the entire RMP range while maintaining the refinement and reliability expected from Audi's flagship design.

Jackal Motorsports offers Stage 1, Stage 2, and fully custom Stage 3 tuning for the D5 A8 and A8L.

The result is a dramatic increase in power and torque across the entire RPM range, sharper throttle response, and a noticeably more responsive driving experience - all while maintaining factory-level safety systems.
