I have the V-6 motor with 4x4. Lookin to get some more "umph" out of my engine. I would like to try and send in the computer to get it chipped, but I don't know if the would be worth the $300+ I was just wondering if anyone else has done this and could tell me how it went. Also, if I did this, and then later came across the money to put a supercharger on it, could the two work in tandem, or is it only one or the other. Any info greatly appreciated. Jim
