What is the difference between a programmer / tuner and a module / chip?
This is one of the most popular questions we get. The difference between the two is that a programmer / tuner installs inside the vehicle via the OBD port and re-flashes the truck with a new program storing the stock program in the programmer / tuner. A chip / module either install under the hood by “piggy backing” the stock plugs and sensors or plugging directly into the trucks ECU inside the truck. Both of these methods in most cases require no cutting, but may require splicing into an under hood harness.
