Any recommendations, I want to upgrade to a 2.5" TF coil lift, 33 or 34 inch tires. I know I'll need to recalibrate etc... Also my JK is brand new so I am not so hot to modify it by reprogramming and be out of warranty, any advice? Do you just set it back to stock when you go to the dealer?

 

depends what your looking for the chip to do. If you want it to have the same amount of power and act like the factory jeep the way you got it...then go with the procal. But if your looking for everything the procal does plus added power then your going to want to go with the superchips. The procal essentially just tells the computer that the shifts need to be longer etc. so when you go up a hill it doesn't keep shifting gears on you. Whereas the superships does that but also messes around with the fuel and valve timing etc. The one real benefit that the procal has that the superchips doesnt is that it resets the esp to what you need.
