The "chip" is not crazy, depending on which one you buy. I personally would recommend a programmer over a chip for two reasons: with the chip in, its in thats it (at least the ones i have encountered thus far); with the programmer, you have different steps of program, stock, towing performance, and even different levels of performance depending on which brand you choose. I also would not buy a kit that is hard wired into the trucks harness, i have personally seen them cause more harm then good. I would recommend one that would plug into your OBII DLC and provide you with not having to mount any boxes or switches, and still give you the adjustability you want. And if you ever need work done to the truck, its a lot easier to plug up and pull the program out, than to remove a box and related harness. Just my thoughts, great looking truck you have there. I assume you have the 7.3 Power Stroke? If so check out the crank sensor on the front of the block, right above your harmonic balancer. If you have a gold bracket, check with your local ford dealer about having the recall on it performed, if you have a silver bracket, your good to go my friend. Just my thoughts and two cents, FWM.
