I just picked up my new 2015 Rubicon 6 speed and would swear the ones I test drove felt a whole lot faster. I am not getting on it all that hard as it is brand new but it seems like under 4,000 rpm the Jeep is a total dog. I am curious as to how much peppier it may feel and how long that may take.

I am going to break it in pretty carefully as I simply prefer to do that but I would think with nearly 300 hp and 265 pound feet or torque it would feel livelier. Maybe issue number 2 below has just left a bad taste in my mouth.

Other than that, the Jeep is pretty cool, minus the defective stereo. The unit will not connect with a phone and voice commands are not being accepted. The dealer thought it may be the microphone so into the shop it went and they replaced the mic from another Jeep. That made no difference so they have traced it back to the head unit or at least that is what they said. So unfortunately I have to drive from Wyoming back to Seattle on my fantasy trip with a stereo that won't connect to my phone AND will randomly switch from AM, to FM, to my iPod. I never thought about testing these items prior to signing on the dotted line so add this to your checklist of things to do before you sign.

Nice looking Rig NC! Try doing a throttle recalibration it may help. I read about it on a different forum. I'm going to try it when I get my JK in a few weeks.

"Throttle Calibration
Throttle calibration can substantially improve throttle responsiveness over "factory standard." Many people notice what appears to be sluggish throttle response or a "dead area" at initial accelerator depression. Throttle calibration can take care of these.
1) Insert ignition key and turn to "ON" (not start).
2) Wait for all idiot lights to go out. Check Engine Light may remain on.
3) Slowly depress the accelerator pedal all the way to the floor.
4) Slowly release the accelerator pedal until it's all the way back up.
5) Turn the ignition key to "OFF".
6) Start the engine.
Most drivers notice an immediate change in throttle response, but depending on your driving style, you may need to repeat this procedure periodically due to the computer's adaptive programming. You likely need to repeat this procedure any time the battery is disconnected."
