I have an 04 intimidator, stock 3.8 supercharged, and I am looking to do a little work on it. What are a few simple mods to do? There aren't any good performance shops around me (that I know of), so the more technical, the much harder they would be. Basic mechanical swaps I can do myself though.

 

Best place to start is a Cold Air intake. it will free up some power and let you hear the s/c whine a little bit. after that probablly a u-bend delete, and a 180*T-stat, thats all i have done to mine so far, more planned when i run into the money, haha
