Yes - the Lambda II 3.3T is a robust, well-engineered engine shared with the Genesis G70 and Hyundai, and it handles Stage 1 calibration safely. The factory tune is conservative, with meaningful headroom on boost, timing and fuelling. We validate on NZ 98 RON and log knock activity throughout the rev range. The Stinger community globally has an extensive tuning track record on this platform - it's a well-understood engine with no surprises.
Yes - the Smartstream 1.6T in the Sportage gains 25–35kW and 50–70Nm on Stage 1. It's not a dramatic transformation, but it meaningfully improves real-world driving - highway merging, overtaking on open roads and pulling away from urban intersections all feel noticeably better. The Sportage's 7-speed DCT gearbox can also be tuned to sharpen shift timing, which compounds the improvement.
A Stinger GT 3.3T twin-turbo on Stage 1 typically gains 40–65kW, taking it from around 272kW to 315–335kW. That moves it into territory that seriously embarrasses more expensive sports cars. The improvement is most noticeable in the 2,500–4,500RPM range where the V6 is most alive - overtaking becomes effortless and the car feels significantly more urgent without becoming aggressive or jerky at normal speeds.
Yes - particularly for models like the Sportage and Sorento that often carry full loads and need confident performance for daily driving. The extra torque reduces the frequency of gearchanges and throttle inputs in everyday use, making the car feel more relaxed rather than more aggressive. For a family SUV that needs to be quick, efficient and comfortable, a Stage 1 tune is a practical upgrade that costs far less than any comparable hardware change.

2020 Audi RS6 - Takapuna
I brought my diesel ute in looking for more pulling power, and the team at Auto Tuning absolutely delivered. The difference in low-end torque is massive; it now hauls heavy loads up hills without breaking a sweat. The biggest surprise has been the improvement in fuel economy during my daily commute. A proper, professional tune.
