The results show a massive increase in torque starting at 2600 rpm. The increase in area through the curve up until 5250 rpm is massive. The peak gain over the baseline is 186 lb-ft of torque at the wheels at 3500 rpm.
Dyno Comp corrects their Dyno Dynamics to read high but so it is important to focus more on the delta here than the peak figures. Approaching 700 lb-ft of torque at the wheels despite the correction factor is still impressive.
For a heavy 5300+ pound car vehicle the GLE63 the increase in torque will get it moving much more quickly and basically be a huge kick in the pants.
The horsepower gain is solid as well but the M157 is definitely more of a stump puller than top end design and it certainly fits the character of a heavy SUV.
