Throttle response

This is not about how to get rid of the lag when hitting the throttle, but the one when you let go off it. I have a JKUR auto and when crawling in 4low it's very hard to control the speed with the throttle. On my previous rigs with cable throttle, as soon as I let go off the throttle, it would almost stop. With the JKUR, when I let go off the throttle, RPMs won't go down for a second or so and then start going down really slow. This makes the Jeep keep moving forward more that I want it to, even if I slam the brakes. There have been a few instances when I have almost rolled over because I had to give it some gas and when the spotter tells me to stop, the jeep keeps driving forward. I'm thinking on keeping one hand on the shifter and quickly shift into neutral next time I'm in such situation, but it would be great if the RPMs would go down as fast as with a cable throttle, that would make rock crawling a lot more fun. So, my question is, does anybody know of a programmer that not only improves throttle response when you hit the throttle, but also when you let go of it?

I don't know. I had the same complaints first driving a jk. Drive a Tj for over 10 years.
Installed the sprint booster for throttle response and eventually tuned the engine.

The engine still hangs rpm but I've gotten used to it and its not a issue no more. On or off road.

It's an emissions thing and I agree it sucks. I just use the clutch in those situations.

I can set my RPM range in 4 LO or 4 Hi with my Hypertech. I don't have that problem at all. It has a bunch of settings.
