If you want more power-you'll have to tamper with the PCM.

Interesting point Johny. I was wondering if the PCM had the ability so sense power output. So the PCM has sensors that actually measure torque levels? Any details on how they accomplish this? Is the sensor(s) in the transmission or at the flywheel? I've seen the huge, massively expensive dynamometers shops use to measure horse power and torque. Just from a technical perspective, it would be awesome to understand how Ford is stuffing such tech under the hood of a truck.
My brother inlaw is a former Ford Master mechanic (now working on Jags). I'll have to hit him up for some details.
