Give the V6 Highlander more confidence in every mile.
Factory calibration can make the Highlander feel softer and slower to respond than its V6 power suggests. OTT improves pedal response, strengthens usable torque, and helps the transmission make more confident decisions while preserving the smooth, dependable character that makes the Highlander such a practical family SUV.

Better response without changing the personality.
OTT does not turn your Highlander into something harsh or difficult to drive. It simply helps the SUV respond more naturally, use its V6 torque more effectively, and make better transmission decisions.
Natural Response
Pedal input produces a more immediate and predictable response without making the vehicle feel overly sensitive.
Usable Torque
Power is delivered more effectively through the low- and mid-range where it matters most in everyday driving.
Better Shifting
Refined transmission behavior reduces hesitation, unnecessary shifting, and indecision on changing terrain.
Daily Confidence
The improvements are noticeable in traffic, on highway ramps, during road trips, and whenever the Highlander is carrying passengers or cargo.
Your Highlander deserves more than a generic tune.
Each supported Highlander receives the appropriate OTT calibration, personalized setup, and a road test before the appointment is complete. The goal is not simply a bigger number—it is a Toyota that feels better every time you drive it.
