Anyone one having similiar issues?
When you say revving, do you mean in neutral or in gear (under load). If it's only under load, chances are you're activating TCS or ECS. The systems will apply brakes and/or cut fuel to keep the wheels from spinning or the car from sliding. Try fully disabling the Advancetrak (Ford's nomenclature for the TCS/ECS systems) by bringing the car to a full stop, depressing the brake pedal with your foot off the throttle, and holding the traction control button on the center console for at least five seconds. You will see a message on the info center stating "ADVANCETRAK OFF."
Try to recreate the issue after this and see how it goes. My bet is that this will shed some light on your issue. You can also put the system in sport mode by depressing the brake pedal and tapping the button twice (works while moving). This will offer reduced intervention from the TCS and ECS systems.
