Here is a link on who can help you tune your PCM for the need your looking for. http://www.pcmforless.com/
As for adding a supercharger, I have on other toy's and also added turbo's and if your going to be using your Truck all year. Your going to run in to issues, unless your going to run low boost and make sure you have a good program to run your engine management system. The main issue is your fuel delivery and timing in the winter months.
If you do run in the warmer climate part of the country, then just make sure your program and fuel delivery is 100% or your looking for a ride home when the crank shaft passes you.
A good Cam set up and PCM program will give the Hp and performance your looking for with the stock transmission. Adding a supercharger also means modifying your transmission to take the extra HP and torque.
Start with a call with the guys at http://www.pcmforless.com/ and ask them what Cam they suggest with a new torque converter to get the HP and performance your looking for to be a daily driver all year. >>>> Not a trailer queen owner![]()
