The biggest difference you will tell when using a Hypertech is putting the factory settings back in for when you take it in for service. I had my JK serviced yesterday, (cam sensor T.S.B.) I had some things to do after I picked it up and could not upload a program until later. Wow... What a dog, it lugs all the time with 3.73 and 35's. Just trying to get on the interstate it seems to lug on the on-ramp. The tranny just doesn't kick down and go. With the program the power management is so much better. Just the slightest press of the thin peddle and it seems to be in the right power-band. It is much more noticeable what the Hypertech does when you remove it after you have been running a program for some time than what it is when you first install it. I'm very happy with the programmer.

I don't think it is too much at all! It actually feels quite normal to me. I had passing thoughts after I ordered the 5.13s that the Jeep would feel like a UPS truck 
Fortunately it's not like that at all.
The *only* time where the 5.13s feel like they are a bit much is if i mash the accelerator at a low speed. The tranny drops down to first ... and there is nothing there. It's pretty close to redline at that point and really has no where to go.
I find that if I just accelerate normally, it will get up and go much, much better than stock.
I haven't had a chance to get out on the highway much. My shop wants me to put 500 city miles on it to break it in. I did have it up to 65 briefly on a secondary road and in overdrive the tach was sitting at about 2500, so I think a 70mph cruise should be comfortable for a long haul.
