Sierra/Silverado LB7 6.6L Duramax


The EFI Live is the professional's go-to when tuning the 2001-2004 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 Diesel Tech's tuning with either a single tune or 5 tunes. The Diesel Techs 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 2001-2004 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.  

Diesel Techs Tunes Available:

  • 0hp
  • 30hp Economy / Tow
  • 50hp Street
  • 100hp Performance
  • 150hp Race

Higher Power levels can be written with the proper supporting modifications. Please state the HP level and the supporting modifications. 

 

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!

“Good product so far. Very pleased. Yawl should recommend the uppipe as the blocking plate on the passenger side uppipe broke the tab weld after 1000 miles. Ordered an uppipe to solve that issue. Fuel mileage up from 12.7 av to 19.8 very satisfied with that. 23 on the highway. All good for now.”
