Overview
The GLC 43 line spans two distinct but attractive AMG platforms, the earlier M276 V6 and the newer M254 four cylinder, both of which respond well to torque and boost recalibration. The older V6 is easier from a flash workflow standpoint, while the new generation needs Bosch MG1 bench support before tuning. Either way the heavy SUV chassis benefits from a much stronger torque curve, making this one of the more commercially useful AMG crossover products.
Key Features
- Two generation coverage
- SUV torque payoff
