I wanna put a supercharger on my 99 F-150 XLT extended cab long bed and make a lightning......?

I want to get the supercharger and i know the lightning and the harley davidson fords use the one that i need however. I also think i need to either change or reprogram the ECU to get it to run right is reprograming a option or would it be easier to just switch the ECU with one out of the lightning. I also herd i could use one out of a Crown Vic Police cruiser i dont know but eventuially i wanna get the ground effects and maybe even a air ride system for my suspention but first thing first what would be the best way to go about my ECU problem
