Take the doors off, hardtop off, add the superchip, and you should notice it becoming "faster"

 

We traded my wifes Expedition EL for a '11 JKU... I was very concerned about the difference in power. Turns out that the 5.4 pushing that huge Expy feels like the same power to weight ratio the JKU has in normal every day driving. I think where the most noticeable difference is on the highway in the 70mph range... The slightest grade has the JKU gasping for air while the Expy would have motored right along. Even with that, it's not that bad and not once has my wife complained that the JKU is lacking power. It's her dd and she's on the road most of the day for work. Her biggest complaint has been general noise in the cabin while on the highway... It makes it tough to utilize the uconnect system...

 

Welcome to the forum, just remember it's a Jeep thing.
There is no horse power, it's all torque.
