The Power Chip is installed by being pushed into the diagnostic port. It's recommended to put a piece of tape over the chip to hold it in place while the PCM is slid back into the truck. To use the diagnostic port in the future, the Power Chip must be removed. The chip learns your driving style and customizes the engine and transmission calibrations to this style. We felt an immediate increase in power but drove the truck for over a week before testing rear-wheel power on the dyno.
