Just need a few pointers.

Hey everybody, i'm getting ready to install a supercharger in my '97 lesabre and was wondering if anybody could give me a few pointers to reduce headaches during installation. I have the correct supercharger, fuel injectors, fuel rails, new intake manifold, gaskets and belts. Is it necessary to swap out the ECU or can i just get it programed? And if anybody has any other tips or suggestions, it would be greatly appreciated. Thanks for your time, i'm really gonna be excited to annhilate those damn ricers even more.
