How to Choose Your Options

The EFI Live is the professional's go-to when tuning the 2011-2016 GM Duramax. The EFI Live system is a tool that allows you to electronically crack open the OE ECU & TCM in your Duramax and allows you to overwrite the stock files with upgraded tunes.

This specific EFI Live will include Unlimited Diesels tuning with either a single tune or 5 tunes. Unlimited Diesels writes their custom tunes for the Duramax in Canada and is highly regarded as one of the best custom tuners for the Duramax engine. Allow you to make safe and reliable power in your 2011-2016 Duramax.

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.
