Before you tune, make sure everything else is in good working order, like your coolers, HPO system, etc. Do the research on upgrades that pertain to your particular truck, and know if you have an early '04 or a later '04.5 build. Other than good maintenance, monitoring with a Scan Gauge II and a pyrometer, or maybe an Edge CTS display only that carries the same diagnostic and data monitoring and pyrometer abilities as the other items integrated in one unit and offers a back up camera too.
