Kia Stinger 3.3 Turbo

Unlocking the Potential of Kia’s Flagship

Kia’s transformation over the past decade has been remarkable. Models like the Stinger, Sorento, and Sportage show just how far the brand has come in design, engineering, and technology. But even with all that progress, there’s still untapped potential hiding within the ECU, and that’s where AutoUpgrades comes in.

Our Kia performance tuning refines the calibration at the heart of the car, optimising boost control, fuelling, and torque management to unlock the performance the hardware was always capable of. The difference is instant: sharper throttle response, stronger acceleration, and smoother, more refined power delivery.

Why the Stinger 3.3 Turbo Responds So Well

The Stinger’s twin-turbocharged 3.3-litre V6 already delivers impressive performance, but the factory software keeps a wide safety margin to suit global conditions. Our calibration narrows that margin intelligently making full use of the engine’s capability while preserving reliability.

Torque arrives earlier, mid-range pull strengthens, and throttle response becomes immediate. The car feels lighter, quicker, and far more eager without sacrificing the composure that makes the Stinger so enjoyable on long drives.

Engineering with Discipline

Just as importantly, our approach keeps everything balanced and factory-refined. All protection systems remain fully active, including knock control and temperature safeguards, ensuring the same long-term reliability you expect from Kia’s engineering.

Our Auckland-based calibration team uses OEM-grade methodology and professional development tools for every ECU we tune. Each calibration is validated and data-logged to ensure consistent performance across all driving conditions from daily commuting to long motorway runs.

More Models, Same Precision

With the Kia Stinger 3.3 Turbo now added to our portfolio, the full Kia range benefits from our precision tuning approach. Whether you’re chasing more responsive throttle behaviour, smoother torque delivery, or outright performance gains, the difference is unmistakable.

Your Kia is already a capable, modern performer but with our tuning, it becomes something truly rewarding to drive.
