You guys weren't kidding about the difference. It does feel like a different car, it's weird. The throttle response seems different in a good way.. and the transmision shifts pretty quick now. At the most, it's about 1,000 rpm drop for me. Also, I was not hassled at all at the dealership I went to. It was Sarasota Ford in Sarasota, Florida. I printed out the paper, told them to follow the directions, and then make sure my cruise control still worked after the reflash and they nailed it in about an hour and a half of waiting time. It's well worth it ladies and gentlemen!
