How's it artifically inflated? You're measuring what's at the wheels. It's not the engine making all that torque, but there is torque multiplication through the TC which is brought at the wheels. Hence 390wtq, not 390 ctq.

Noone said that this engine paired to a manual gearbox would make these numbers, it would probably make more peak hp, less peak tq. Now your way of thinking, does this mean these horsepower / top end torque numbers artifically low due to the higher parsitic loss of a hydraulic automatic?

Edit: I kind of see where you can come from. Using like a road dyno software this becomes evident. If you are measuring how quick it can accelerate RPMs, then yes, this 'slip' is shows up as torque rise/then dip. However, I am very sure it measures torque simply by how quick it can accelerate the rollers and then assigns RPM datapoints to it afterwards, hence this is real torque. You could always measure it torque vs. time and see what happens.
