WHAT IS THE BEST PROGRAMMER FOR MY TRUCK FOR FUEL MILEAGE?
Actually there is no “best programmer” for any truck. Choosing the right programmer is based on what you are using the truck for and what your main objective is with it. Now there are some units that are better than others based on what you are looking for, but the first step is deciding what you want out of your truck.
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.
WHERE CAN I FIND THE BUILD DATE ON MY TRUCK?
Most build dates can be found on the information label on the inside of the driver door jam. This label will tell you anything from the VIN number to the recommended tire pressure.
WHAT IS A CORE CHARGE?
A core charge is an acronym for "Cash On Return". These are rebuildable parts that can usually be redeemed for a portion of their original purchase price. Most companies will reuse the case of a transmission, the core of a valve body or even an internal part of a torque converter that is either no longer available or much to expensive to buy new and can be reused on the newly manufactured part. These charges are refundable though once you send in your original part.
