What is Tuning?
By choosing a custom tune, you can refine engine and transmission parameters beyond standard factory settings. Many owners seek custom tuning to maximize thermal efficiency and optimize combustion timing. By refining the combustion cycle and streamlining internal engine processes, we can extract more energy from the fuel than previously possible. This calibrated tuning ensures the engine operates at its peak mechanical potential, often resulting in improved throttle response and enhanced overall efficiency.
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.

2016-2022 2.8L Duramax CCS EFILive Tune Package
Overall rating: 5.0 / 5 from 18 reviews.
The experience was great. Had a few small issues to work out which wasn't a big deal. The power is great I got the 90hp tune and transmission tuning. When your on hold the skit is worth is funny and is alot better then the crappy music most places have.
The CCS tune uploaded without a hiccup, fired right up without any codes. So far so good. Waiting for a road test to see the finished product once the exhaust work is done.
Was interesting and fairly easy to use. I managed to figure it out, even with my limited computer literacy.
you guys made the confusing part of this whole experience super easy, thank you!
Worth every penny!! Great staff as well..
The Tune File loaded quickly and easily after a couple questions were answered by DDC. so far so happy, seems like a reputable shop with knowledge and support. Thanks!
It was a steep learning curve, 3 years since I last used windows. I Used bootcamp on MacBook Air. Lots of support from DDC. Very patient with some of my questions. I have not driven my truck much, about 75km with the new tunes 25HP and TCM, I have noticed the change and looking forward to my trip next week. Will be loaded up then
Part came fast Perfect fitment Exactly what I was looking for When and if I had any issues staff on telephone were super helpful and walked me through it ! Highly recommend
Tune worked great. Lots of power, fuel economy improved. Delay in acceleration gone.
Tuned both the engine and transmission and then performance has been outstanding. The staff at Dirty Diesel answered all my questions quickly and got out the products quickly even over the holiday season. Thanks again Dirty Diesel! I will be referring my fellow diesel drivers your way!
