The M276 twin turbo 3.0 liter V6 in the Mercedes-AMG C43 models may not be a real handbuilt AMG motor but it certainly responds well to tuning. In the forums owners have discussed the OE Tuning tune for the M276 DELA30 positively and this graph certainly supports their reasoning.

The C43 is rated at 362 horsepower and shows 327.3 wheel horsepower stock. This is bumped up by 58.6 wheel horsepower for a total of 385.9. The mid-range shows the greatest gains.

The factory torque figure is rated at 384 lb-ft. The calculated crank torque baseline reads 480 lb-ft which is much more than stock. Frankly, BenzBoost can not explain why the torque reading is so high.

Regardless, OE Tuning is picking up large gains on the M276 DELA30 Turbo platform.
