The EA824 4.0T V8 is a strong foundation for performance, and our staged ECU/TCU tunes unlock its full potential while maintaining daily drivability. Each stage is carefully calibrated by our global team to deliver smooth, linear power with OEM-like refinement.
Stage 1 is the ideal entry point for EA824 owners who want a dramatic increase in performance without changing any hardware. Optimized boost, ignition, and fueling deliver significantly more usable power and torque across the rev range.
Final Output: 550 HP / 590 lb-ft TQ
Fuel Requirement: 93 Octane
Hardware Requirements: None (stock hardware compatible)
Installation: Flashable at a dealer or at home with the FlashZilla PRO tool
⚠️ Note: While all stages are carefully designed for reliability, these power increases place additional stress on the factory driveline components, especially under extreme launches. Customers should be mindful of maintenance and supporting upgrades to ensure long-term durability.EA824 4.0T Tune Comparison

Stage 2 pushes the EA824 further by incorporating key supporting hardware. Alongside the ECU calibration, a TCU tune (minimum Stage Plus) is required to handle the increased torque and optimize transmission behavior.
Final Output: 570 HP / 620 lb-ft TQ
Hardware Requirements: High-flow downpipe
Recommended Upgrades: Intercooler & intake system
TCU Tune Requirement: Stage Plus or higher
Stage 3 is for enthusiasts who want to push the EA824 beyond its stock limitations. This is a fully custom setup that requires upgraded turbochargers and supporting hardware. With proper fueling and cooling, Stage 3 delivers supercar-level performance while maintaining OEM-like drivability.NOTE: This is a custom-built tune that will require logging/ dyno time

Price: FREE with any ECU Tune purchase
Minimum Requirement: Must be flashed for Stage 2 or Stage 3 ECU Tunes
Flashing Options:
Dealer installation
At-home flashing with the FlashZilla PRO tool
⚠️ Note: Stage 1 tunes can run on a stock TCU, but Stage 2 and Stage 3 require the Stage Plus TCU Tune to safely handle increased torque output.
