FOR IMMEDIATE RELEASE

OVERLAND TAILOR TUNING RECEIVES CARB EXECUTIVE ORDER FOR TOYOTA AND LEXUS 3UR-FE CALIBRATIONS

OTT achieves significant emissions-compliance milestone for its naturally aspirated 5.7L V8 engine calibrations.

BIRMINGHAM, ALABAMA — November 6, 2026 — Overland Tailor Tuning (OTT) is proud to announce the issuance of California Air Resources Board (CARB) Executive Order D-883-1, granting an exemption under Section 27156 of the California Vehicle Code for its OTT Torque Tune calibrations on select Toyota and Lexus vehicles equipped with the naturally aspirated 5.7-liter 3UR-FE V8 engine.

The Executive Order establishes that OTT's specified calibrations have been found not to reduce the effectiveness of applicable vehicle pollution control systems and are therefore exempt from the prohibitions of Section 27156 for the vehicles identified in the order.

The exemption encompasses select model years of the Toyota Tundra, Toyota Sequoia, Toyota Land Cruiser, and Lexus LX 570, representing a significant achievement in OTT's continued development of emissions-compliant automotive calibrations.

The approved applications include calibrations designed to improve vehicle performance, particularly mid-range torque, shifting and throttle enhancements.

"We've been working toward this Executive Order for the 3UR-FE platform for more than two years, and we're extremely excited to finally bring these emissions-compliant calibrations to the marketplace," said John Gobbels, CEO of Overland Tailor Tuning.

"Our objective throughout this process was straightforward: retain the driving characteristics, power, torque, and overall refinement that OTT is known for while meeting California's stringent emissions requirements. We weren't interested in compromising the quality of our calibrations to accomplish that goal. We wanted to demonstrate that exceptional drivability and emissions compliance can coexist."

"OTT has invested considerable time, engineering resources, and testing into this effort. Our clients trust us to provide calibrations that are not only enjoyable to drive but professionally developed, thoroughly tested, and safe for their vehicles. This Executive Order represents another important step in delivering on that commitment."

The issuance of Executive Order D-883-1 marks an important milestone in OTT's ongoing investment in emissions-compliant calibration development. As regulatory requirements continue to evolve, OTT remains committed to providing professionally engineered solutions that preserve the driving experience its clients expect while maintaining applicable emissions-system protections.
