Maximize the "Go-Kart" Thrill of Your Mini

Small size. Big attitude. Massive potential.

You didn't buy a Mini to blend in; you bought it to have fun. Whether you are zipping through city streets in a Cooper S, rallying in a Countryman ALL4, or enjoying the open air in a Convertible, your Mini is designed to put a smile on your face. But let's be honest: the factory tuning (especially on non-JCW models) often leaves the car feeling a bit hesitant off the line.

The Stage 3 "Rally-Spec" Performance Module is the adrenaline shot your Mini needs. Engineered to unlock the hidden potential of the BMW-sourced Turbo engines, this OBDII module eliminates turbo lag and sharpens the throttle, ensuring your engine finally keeps up with your handling.

✔ JCW-Level Response. ✔ Fix "Green Mode" Lag. ✔ Boost Your Boost.

Why Upgrade to Stage 3?

• Unlock the "S" Power: Safely unlock up to +35 Horsepower and +40 ft·lbs of Torque. Feel the difference when you mash the pedal to pass traffic or blast out of a corner.
• Telepathic Throttle: The "rubber band" delay in modern Minis is a buzzkill. We sharpen the signal to make the connection between your foot and the engine instant—just like the classic mechanical Minis.
• Countryman & Clubman Torque: For the heavier 4-door models, the added low-end torque makes the car feel significantly lighter and more eager, especially with a full load of passengers.
• Smoother Shifting: Helps the Automatic and DCT transmissions decide on a gear faster, preventing that awkward pause when you need sudden acceleration.
• Universal Union Jack Compatibility: Works seamlessly with the Hardtop (2 & 4 Door), Countryman, Clubman, Convertible, and Coupe/Roadster.
• Plug & Play Fun: Installs in under 60 seconds via your OBDII port. No tools, no mechanic, and no greasy hands.

Smart Tuning for the Bulldog Stance

Modern Minis utilize sophisticated BMW powertrains. The Stage 3 Tuner uses adaptive mapping to unleash them.

The Turbo Advantage: Whether you have the 1.5L 3-cylinder or the 2.0L 4-cylinder, the factory detunes these engines for fuel economy. Our module optimizes the boost spool-up, giving you a wave of torque that hits hard and early.

For the Manual Transmission Purist: It makes rev-matching easier and takeoff smoother, preventing bogs and stalls.

Frequently Asked Questions

I have a JCW (John Cooper Works). Will this help?
Yes! Even the JCW has factory safety buffers. The chip stacks on top of the JCW tuning to sharpen the throttle response even further and optimize the upper RPM range.

Will this work on the base model (3-Cylinder)?
Absolutely. The 1.5L Turbo 3-cylinder is a spunky engine that loves a bit of extra boost. The chip makes the base Cooper feel much more like a Cooper S.

Does it affect "Sport" Mode?
It enhances it. When you flip the toggle to "Sport" (and get the "Maximum Go-Kart Feel" message), the chip’s aggressive map combines with the stiffer steering for an incredible driving experience.

Is installation hard?
It is effortless. The OBDII port is located under the dashboard on the driver's side (usually near the hood release lever). Simply plug it in. It takes less than 60 seconds.
