Does anyone know which one of the tuning devices work best for the JK's? Is there someone that makes the best tunes for them?

I have a 2006 GC SRT8 and have the diablo tuner and a chip from modern horsepower that makes a HUGE improvement in performance. I take it to the track all the time and got much better times after the tune.

Are there any tuners than can be used on two vehicles at once? I was leaning toward the infinity but i'm new to the wranglers and wasn't sure if diablo is as good as they are with the SRT engines.

Any help or suggestions would be greatly appreciated. The SRT is covered up for winter and I need to get some better performance out of my JK.

 

My personal opinion best module for the JK is the ProCal. It has only the features that matter. Superchips Hypertech, Jet, etc make those "performance" chips. For the money they all seem to be proficient

 

Great, thank you. I'm not gonna be racing the thing or anything like that. I just don't want to have to switch out of overdrive to go up a hill on the highway. Right now, i either have to shut off the overdrive or give it gas to kick it down a gear to get a long incline. If I have a stiff headwind I have to stomp on the gas to stay moving at 65mph.

The diablo made huge difference in my SRT. The shift points are so crisp and give me a lot better throttle response.
