Welcome to FTE dondon623. Slow throttle response is one of the complaints with the 5.4. I purchased a Superchips tuner from this site's store ( www.motorhaven.com), and it not only eliminated the lag all together, but it also gave me more power (= more fun to drive), and I actually gained 1mpg. All in all, I am very happy with the unit. It might be something for you to look into.
