QX56 vs. Titan
The standard 5.6-liter DOHC Endurance V8 produces 315 horsepower and 390 lb-ft of torque in the QX56.
Why does the QX56 have more hp and torque? Is it just the ecu or are there mechanical reasons for the difference? If it's the ecu, would swapping a QX56 ecu with the Titan's give us those same numbers?
