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 that 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.
A single tune option is perfect for customers who are just looking for a mild tow or economy tune and do not foresee the need to switch tunes. The truck will always run it much like the stock tune, perfect for customers who are not the only ones driving their trucks. We can set up a single tune to any power level or configuration.
The DSP5 option is great for customers who want the ability to turn up and down the power of a tune as a result of the changing circumstances in which you plan to use the truck. For example, if the truck is empty you can turn up the power to have a little fun, then turn it down when hooking up to your holiday trailer to minimize stress on the drivetrain.
Remote custom tuning has never been easier! The EFI Live AC3 allows you to receive custom tune files via email, download them to your AC3, and then flash them onto your vehicle. So as long as you have an internet connection and access to a computer, you can throw these tunes on from anywhere!

QUESTIONS & ANSWERSAsk a Question
What does the Transmission tuning do?
TCM Tuning increases the line pressure, this puts more pressure on your clutch packs and prevents them from slipping which can cause excessive early wear on clutch disks. It will also change the shifting points to match the new tuning which helps improve the overall driveability.
Can the tuner and the tunes be transferred to someone else if the truck gets sold?
No, these tunes get written to a Vin number so they are paired with the truck.
