3.8 2014 vs 2015

[GJEMD]

I read the 2015 version of the 3.8 drops from 333 HP to 311 HP in a larger vehicle. I wonder if they have retarded the timing a bit to deal with intake valve deposits. I can't think of any reason to reduce HP in a larger vehicle.

My understanding is that although HP has dropped slightly, the engine mapping has been revised to produce slightly more torque but spread across a wider rpm range. Since torque is far more important than HP for everyday stop-and-go driving, this should benefit real-world performance. I doubt the car will be any slower in its 0-60mph acceleration.
