Clean Stage 1 remap delivers 24 kW and 110 Nm gain at the wheels

The GLC43 AMG responds well to a software-only tune. This 2020 AWD model picked up 24 kW at the wheels, lifting output from 208 to 232 kW, while torque jumped from 410 to 520 Nm. No hardware changes required.

The torque gain is the real story here. An extra 110 Nm transforms mid-range response without asking anything of the factory hardware. Useful for overtaking on highway runs or just making the vehicle feel considerably more eager in daily use.

Straightforward remap work. The platform takes the changes cleanly and the result is repeatable. Good option for customers after a noticeable lift without touching the intake, exhaust, or cooling.

Common questions
Does this tune require any supporting modifications?

No. This is a Stage 1 software-only remap with no hardware changes required. The factory setup handles the tuned output.

What fuel should the customer run after the tune?

Fuel type wasn't recorded for this build, but most AMG tunes of this era are calibrated for premium 98 RON as a minimum. Confirm with your customer before delivery.

Is the torque gain safe on the factory drivetrain?

The tune lifts torque to 520 Nm from 410 Nm. The GLC43 drivetrain is well built, and this remains a conservative Stage 1 file, but longevity always depends on how the vehicle is driven and maintained.
