less than a month ago I purchased a 2014 JK unlimited and within 2 weeks I installed a 2.5 inch Rubicon Express lift on 305 70 17 Nitto Terra Grapplers. One thing I noticed before I installed the lift is that the jeep shifts gear at a high RPM I know there are modules out there to fix this. What are others doing out there for RPMs and improving MPGs? Also I need to correct the speedometer it is off by 3 mph now. Any input is greatly appreciated.

not sure if its 2014 capable yet but check out the superchips flashpaq. i have run this tuner on 2 jeeps with noticeable improvements. it will coreect your shiftpoints, speedometer, has several different performance tunes you can run and many other features. The procal is nice also and half the cost of the flashpaq however it is just a programmer it does not have any performance tunes so you get what you pay for

Thank you, I have also seen a lot on the Jet Performance Module, but can not find any reviews. I will look more closely in to the flashpaq

Stay away from the Jet chip. You need something that will allow you to adjust tire size etc.

Thanks I am sticking with Superchip. I was on a chat with Quadratec and they reccomended the Flashcal any luck with this they say it can program my shift points but it does not say anything about that on the description. Flashpaq or flashcal?

Flashpaq I know can modify shift points and a ton of other stuff I don't mess with. Flashpaq is the better of the 2
