Re: 4.0L High output

Slight difference on the camshaft lobes and mostly computer software in the PCM was changed. Some differencen on the engine wiring too for the sensors. EGR valve and knock sensors were taken out but some sensors were added to increase response and performance for the H.O. 4.0.
