How Do Mercury Performance Chips Work?
Rocket Chip performance chips connect through the vehicle’s OBD-II diagnostic port and communicate with the engine-management system. Rocket Chip performance chips use vehicle-specific programming designed to adjust fuel and timing-related parameters to improve throttle response and overall engine performance. The device remains connected while in use and can be removed with the engine off when needed for servicing or diagnostics.
