The Best or Nothing... Now Faster.

German engineering is legendary. Factory restrictions are not.

Your Mercedes-Benz is the pinnacle of automotive engineering, designed to dominate the Autobahn. However, whether you drive a nimble C-Class, an executive E-Class, or a commanding GLE/GLS, you’ve likely felt it: that split-second delay when you step on the gas. This "electronic lag" is the result of strict emissions tuning that holds your engine back.

The Stage 3 "Autobahn-Spec" Performance Module is the key to unlocking the true potential of your Star. Engineered to optimize Kompressor, Biturbo, and BlueTEC engines, this OBDII module bypasses the restrictions, delivering instant acceleration and the effortless power that a Mercedes is meant to have.

✔ Eliminate Throttle Lag. ✔ Wake Up the Biturbo. ✔ AMG-Level Response.

Why Upgrade to Stage 3?

• Unleash the Output: Safely unlock up to +50 Horsepower and +60 ft·lbs of Torque. (Results are massive on C300, E350/450, and GLE450 models). Transform your luxury cruiser into a sports sedan.
• Fix the "Eco" Hesitation: Mercedes transmissions (7G and 9G-Tronic) often start in 2nd gear or hesitate to downshift to save fuel. We sharpen the signal to make the car react instantly when you need to merge.
• Diesel Dominance: For BlueTEC and CDI owners (Sprinter/GL/GLE), the massive increase in low-end torque makes towing and hauling heavy loads feel effortless.
• AMG Agility: For AMG owners (C43/C63/GLC43), this chip stacks on top of the factory performance tune, sharpening the throttle blips and maximizing mid-range boost.
• Universal Star Compatibility: Works seamlessly with the C-Class, E-Class, S-Class, CLA, GLA, GLC, GLE, GLS, and G-Wagon.
• Plug & Play Luxury: Installs in under 60 seconds via your OBDII port. No tools, no mechanic, and no dirt on your hands.

Smart Tuning for Stuttgart's Finest

Mercedes ECUs are some of the most advanced in the world. The Stage 3 Tuner uses adaptive logic to enhance the driving dynamics without sacrificing comfort.

The Biturbo Advantage (C300 / E450 / GLC): Modern Mercedes turbo engines are heavily detuned. Our module optimizes the boost curve, reducing the time it takes for the turbos to spool up. This gives you that "big engine" feel, providing immediate power at 2,000 RPM.

The Smoothness Factor: Unlike cheap chips that make the car jerky, the "Autobahn-Spec" maintains the silky smoothness of your transmission while ensuring the power is there the moment you demand it.

100% Safe & Warranty Friendly

We know you value the resale value and warranty of your Mercedes. The Stage 3 Performance Chip is 100% safe.

Invisible Engineering: The device operates as a piggyback system. It does not permanently "flash" or rewrite your ECU. If you need to visit the dealership for service A or B, simply unplug the unit. Your Mercedes returns to stock factory settings instantly, leaving no digital footprint.

Frequently Asked Questions

Will this work with Dynamic Select (Agility Control)?
Yes. It enhances it. In "Comfort" mode, the car will feel more responsive but still smooth. In "Sport" and "Sport+" mode, the chip fully unleashes the extra horsepower and sharpens the throttle response for a truly spirited drive.

Does it work on AMG models?
Absolutely. Even AMG vehicles have safety buffers in their mapping. The Stage 3 chip tightens the throttle response and optimizes the boost in the mid-range, making your AMG feel even more aggressive.

Will it affect my Sprinter Van (Diesel)?
Yes, and it is highly recommended. For Sprinter owners, the chip provides the torque needed to merge onto highways safely when fully loaded, and often improves fuel economy by keeping the van in higher gears.

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