What is Tuning?

By custom tuning a truck, you are given the ability to modify countless parameters to the engine and transmission operation that OEMs had to produce the stock tunes you started with. The number one reason customers choose to tune their trucks is fuel economy.

Just by changing the rate of the burn inside the combustion chamber and removing EGR gases (if applicable) from the burn we can extract more energy out of the fuel than was otherwise possible. By extracting more energy out of the fuel we get increased fuel mileage as less fuel is required and an increase of power.

Different power levels can be written under request and/or depending on modifications to the vehicle. As all tune files are custom; this will give you a general idea of what you could or can get.

• Level 1 0 HP
• Level 2 60 HP
