Stage 2 AI Performance Chip Module OBD2 for Buick – Adaptive Power & Fuel Efficiency

Modern Luxury Meets Hidden Performance

Buick has redefined itself with a lineup that blends premium "QuietTuning" luxury with modern versatility. Whether you drive the compact and spirited Encore GX, the sporty Regal GS, or the family-hauling Enclave, your vehicle is engineered for comfort. However, to maintain that ultra-conservative smooth ride, factory ECU tuning often sacrifices throttle response and raw power, making your Buick feel heavier and more sluggish than it actually is.

The Stage 2 SMARTTUNE with AI Technology is the upgrade your Buick deserves. This is not a noisy, aggressive modification; it is a refined, AI-driven OBD2 module that enhances your engine's efficiency and output. It learns your driving style—whether you are commuting in the city or towing on the highway—to unlock the responsive, confident power that lies dormant in your engine.

Optimized for Ecotec and V6 Performance

Buick’s modern powertrains, from the 2.0L Turbo Ecotec to the robust 3.6L V6, are capable of much more. Our AI technology safely optimizes the ignition timing and boost pressure (on turbo models) to deliver power that is both smooth and authoritative.

• Wake Up Your Turbo: For Encore and Envision owners, the 1.4L and 2.0L Turbos can suffer from hesitation off the line. We optimize the signal to provide up to 50% better throttle response, giving you the confidence to merge into fast-moving traffic without delay.
• Haul with Confidence: The Enclave is a fantastic hauler, but it can feel strained when fully loaded. Gain up to 28.6 ft·lbs of added torque, making towing boats or carrying a full cabin of passengers feel effortless.
• Transmission Smoothness: Designed to work in harmony with Buick’s 9-speed automatic and CVT transmissions. The chip ensures shift points are crisp yet smooth, maintaining the luxury ride quality you paid for.
• Commuter Efficiency: Optimize your daily drive. By refining the air/fuel mixture for maximum efficiency, the chip can help deliver up to a 2 MPG increase, saving you money at the pump.

Universal Compatibility: From Regal to Enclave

The Stage 2 SMARTTUNE utilizes the standard OBD2 port (standard on 1996+ models), ensuring compatibility with both classic cruisers and modern crossovers.

• Models Supported: Encore, Encore GX, Envision, Enclave, Regal (Sportback/TourX/GS), LaCrosse, Verano, Lucerne, and more.
• Engine Tech: Fully compatible with Ecotec Turbo, Naturally Aspirated V6, and mild-hybrid powertrains.
• Adaptive Learning: The onboard AI processor analyzes your specific vehicle's sensor data over the first 200 miles, creating a custom map that balances power with Buick’s signature smoothness.
