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 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.

Single Tune

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.

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!

The AC3 is more than just a 'generic handheld', the AutoCal delivers EFILive's renowned scan tool for your use. This allows for the collection and transmission of logged data back to the tuner for analysis. Have a DTC code that you're worried about? With this AutoCal, you also have the ability to diagnose and clear codes.

• In order to have the tune files written specifically for your truck, we will require you to send us a "stock file" which can be obtained by utilizing the EFI Live Autocal once you receive it.
• In order to get you your EFI Live sent to you as soon as possible, please input the requested information. We cannot ship your EFI Live until all this information has been received!
