EFILive Software
The factory uses powerful computers to control the engine and transmission functions on board your truck. They don't do this because it's cheap, they do it because this type of system offers the best drive-ability, lowest engine noise, and the ability to continuously adapt the power train to changing driving styles and operating conditions.
We at Duramaxtuner.com use this software because it allows us the same degree of engine control used by the engineers in GM's lab, and it does so with an interface that is relatively easy to use. With custom tuning the performance enthusiast doesn't have to compromise comfort and drive-ability to run a 450-800+ rwhp truck on the street. Dream up the engine combination and operating conditions then use Duramaxtuner.com and EFILive to achieve it.
