OTT's calibrations are designed and tested to make your truck drive the way the factory never quite delivered. On supported platforms, the tune can deliver:
The factory calibration is a compromise, tuned for emissions cycles, global fuel, and the mildest possible owner, not for your tires, your load, or how you actually drive. A generic "canned" flash swings the other way and ignores your exact platform and modifications. OTT sits where you want to be: a platform-specific Overland Tailor calibration, dialed in person to your year, engine, tire size, and setup, with your factory emissions systems left fully intact.

OTT stands for Overland Tailor Tune, the calibration line from Overland Tailor Tuning. It is a custom ECU and transmission tune developed for specific Toyota and Lexus platforms, not a one-size-fits-all flash.
Yes. Every OTT calibration is matched to your exact platform, engine, and model year, then installed and dialed in person to your tire size, gearing, and modifications, never uploaded blind or remotely.
On supported platforms the tune frees up usable, real-world power and torque through smarter throttle, VVT-i, and octane-learning strategies. The bigger day-to-day win most owners feel is drivability: sharper response and decisive shifting.
Yes, and it is one of the most common reasons owners tune. Larger tires, added weight, towing, and hilly driving all confuse the factory shift logic; the calibration corrects shift points and tow-haul behavior so the transmission stops hunting.
Your factory emissions systems stay fully intact. Every calibration is verified with a 5-gas analyzer during drive-cycle testing and is EPA-compliant in every state. We never disable check-engine lights and do not tune off-road-only vehicles.
OTT calibrations start from $400 to $550 depending on your platform, with custom and supercharger paths priced higher. Use Find Your Exact Tune for your exact price, or see the full OTT tune pricing breakdown.
Supported platforms include the Toyota Tundra, Tacoma, 4Runner, Sequoia, Land Cruiser, and FJ Cruiser, plus the Camry, Highlander, and RAV4, and the Lexus GX, LX570, RX350, and LS460. Use Find Your Exact Tune to confirm your exact year and engine.
