Kia has moved far beyond its utilitarian past, and the Stinger is the clearest proof. With rear-wheel drive balance, turbocharged engines, and solid build quality, it delivers genuine performance credentials. Yet even with this strong foundation, factory calibration leaves potential untapped. At Auto Upgrades, we apply OEM-level methodology to refine the Stinger’s ECU and TCU, unlocking gains that are measurable, safe, and consistent.

Kia Stinger Performance Tuning Auckland

Our tuning process is precise and disciplined. Using advanced calibration methods, we optimise fuelling, ignition, torque control, boost strategies, and gearbox behaviour where required. The result is performance improvements that integrate seamlessly with the Stinger’s character:

• Significant horsepower and torque increases across the rev range
• Sharper throttle response and reduced turbo lag
• Gearbox optimisation for faster, more accurate shifts
• Stronger midrange torque for confident overtaking
• Factory-level smoothness and reliability maintained

Every calibration is developed with the same engineering discipline used by OEMs. This ensures that drivability and refinement are not only preserved but enhanced, while extracting the full potential from Kia’s turbocharged platforms.

Models Covered

We specialise in the Stinger range, including:

• Kia Stinger 2.0T – refined for stronger torque delivery and sharper throttle control, making everyday driving more responsive.
• Kia Stinger 3.3T V6 – twin-turbocharged power calibrated to deliver exceptional performance while retaining full reliability.

Engineered for Precision

At Auto Upgrades, tuning is based on proven methodology and OEM-level practices. By refining the core calibration parameters with accuracy, we deliver a Stinger that performs with greater confidence, sharper response, and seamless power delivery. The result is a car that drives as Kia intended—only with its true potential realised.
