For Toyota Highlander owners looking to enhance their daily driving experience, the Overland Torque Tune (OTT) offers a significant upgrade over the factory calibration. Specifically designed to optimize the 3.5L V6 engine (2GR-FE and 2GR-FKS, depending on the model year), OTT tuning focuses on improving throttle response, refining transmission shift points to reduce “gear hunting,” and delivering a smoother, more accessible power band. This results in a more responsive and enjoyable ride, whether navigating city streets or tackling highway stretches, ultimately unlocking the full potential of your Highlander’s powertrain.
