Datamaster is hands down the BEST mod that you can buy for your truck. Without a datalogger of some sort, you are really guessing how well your truck is running or what is wrong with it. I got it a few months ago and I should have bought it before anything else. You can download it free here
http://akmcables.com/ and get 20 trial runs before you have to fork over some moolah. Only problem is that you have to have a cable to connect the Assembly Line Data Link (ALDL) to the serial port on your laptop. You can get the cables from the link as well.
BTW, if you have a hard time finding the link to the Datamaster download, this will take you straight to it
