If you're looking for a product to improve throttle response, that extra power when towing, race down the track, increase fuel economy, or just improve the overall driveability of your truck then the Evolution is the option. Not only do you get these increase performance features but you get a monitor that offers a clean simple solution for gauges like EGT (exhaust gas temperature), Boost readings, transmission temp, load percent, percentage of fuel left, and more with the expandability to even add more with our EAS (expandable accessory system) or Edge's backup camera.
