Anyone know what the real stock horsepower/torque numbers are for the C450? I keep seeing on a few places online that it's somewhat underrated from the factory.

No way of really knowing an exact number without pulling the motor and putting it on a dyno. Even then you'll get different numbers based in environment, dynos, etc. A chassis dyno will give you wheel torque/hp numbers, but again too many variables that can give wild swings in numbers. Plus with a chassis dyno you'll have drive train loss. Usually for awd cars it's calculated at 20-25%, but that's not exact.
