I'm wondering if any of these chips are worth it or if they will skrew up your jeep
Do a good tune up!!! Plugs, wires, cap and rotor!!! Oil change and filter then you should see improvement! Also try running Lucas treatment in your gas or a octane booster every once in a while!!Itsaj33pthing said:ive got a 4.0 in my automatic jeep but its like it doesnt have the power like it use to. how can i get my power back?
