Next-Generation AI Performance Tuning

Modern BMW engines are highly sophisticated but often detuned from the factory to meet generic global regulations. The Stage 3 JDM Pro-AM Tuner unlocks the actual potential of your specific vehicle.

Unlike cheap resistor chips that simply trick a single sensor, this module acts as a sophisticated piggyback computer. Once plugged into your OBDII port, it downloads real-time data and studies your driving style for 1-2 weeks. It uses active algorithms to optimize ignition spark advance, fuel maps, and transmission shifting.

The result? A smoother idle, enhanced towing power for X-Series models, and a throttle response up to 50% faster. It is the most advanced active algorithm available for both street and track performance.

Designed for Every Configuration: Whether you have a manual or automatic (Steptronic) transmission, or aftermarket parts like cold air intakes and exhaust systems, the Stage 3 chip adapts to your setup perfectly.

100% Safe for Your Engine & Warranty

We know you value the engineering of your BMW, which is why safety is our priority. The Stage 3 Performance Chip is 100% reversible. If you need to visit the dealership for service, simply unplug the unit, and your car returns to stock factory settings instantly. It leaves no footprint on the ECU.

Will this void my warranty? No.
Protected by the Magnuson Moss Warranty Act (US Code – Title 15, Chapter 50, Sections 2301-2312), your vehicle’s factory warranty cannot be voided simply for adding aftermarket parts. This device does not permanently rewrite your factory software.

Frequently Asked Questions

Do I need special tools to install this?
No! This is a true plug-and-play device. It plugs directly into your OBDII port (usually found under the dashboard on the driver's side). No wires to cut, no sensors to splice.

What is the warranty?
We stand behind the quality of our engineering with a comprehensive Lifetime Warranty. If the unit ever fails, we will replace it. We also include a 100% Money-Back Satisfaction Guarantee.

Does this work on sDrive and xDrive BMW models?
Yes, the chip works on both Rear-Wheel Drive (sDrive) and All-Wheel Drive (xDrive) configurations.

Is this just a resistor in a box?
Absolutely not. Cheap $20 chips are often just resistors that trick the air intake sensor. The Stage 3 module uses a multi-core processor to read High-Speed CAN Data inputs 500 times a second to safely optimize air/fuel ratios and timing.

What if I'm not happy with the performance?
You are covered by our money-back guarantee. If you don't feel the power, send it back for a full refund. You have nothing to lose and a lot of horsepower to gain!
