4Runner 5th Gen. 2010-2023

The 2010–2023 Toyota 4Runner (5th Gen) is a legend in its own right: renowned for its durability, off-road capability, and long-term reliability. Most owners feel it performs “OK” out of the box — but there’s a surprising amount of untapped potential under the hood. With our exclusive MCB calibration, we bring that hidden performance to life. By enhancing throttle response and fine-tuning engine parameters, we transform the 4Runner into a smoother, more responsive, and noticeably more powerful machine—on the pavement or on the trail.
