The original question did not come with a budget constraint or cost ceiling for the mod.
I agree with Swathdiver. A Black Bear tune.
While the supercharger option is compelling, to fully utilize its capabilities will require several additional 'sub-mods', such as a new cam, etc., even if it comes in a kit.
For about $600, the Black Bear tune will get you improved performance in the ECM and TCM, improving overall driveability, and making the driving experience much more fun. Plus, you get free lifetime of your truck opportunities to update the tune, in the event that you pursue additional performance-related mods in the future.
