I agree with Brazen. When the engine needs to start, (sometimes between 20-30 mph )and you push a little harder on the accelerator the engine seems to be higher rpm's This is quite noticable and annoying. Before the update the rpm's were much lower and the car was therefore quieter. The service manager at the dealer I dealt with called some Ford hotline where an engineer told him that nothing was wrong. It's definitely not the same. Also I believe the gas milage is now overstated. Before the update it was a little understated.
