Keep in mind if you've got the 4.6 smaller motor, depending on your year. 99 and newer had only 240 horses, less on 97,98. Mine has 260 with the bigger 5.4 motor. Trying to propel a 5800 pound sheet metal brick down the road isn't easy, especially climbing grades. Mine feels fine till I climb a freeway grade. The newer 05-08's got bumped to 300 hp, 09-14 are the zippiest with 310 ponies. Considering your engine if the smaller one, you never stated a year or motor in your posts, was actually put in Crown vics and mustangs, vehicles that are 2,000 pounds lighter, it's amazing they torque along as well as they do.
