Quick Ship SKU #: SCT-7416 SCT X4 Power Flash Programmer 06-10 GM Duramax

Props to GM that over 2 decades of the 6.6L, they managed to bring the Duramax from 300 horsepower and 520 lb-ft of torque to the modern era of 445 rear wheel beef and 910 ft-lbs of "move it buster." But, if you're reading this, you may not own a modern Duramax. That sharp looking 06-10 you've got there is what's now called classic. Do you want to give your seasoned machine the "performance enhancement" treatment to juice up your numbers? A near critical starting point is with that fancy-pants computer. With the ability to press buttons and a desire to make big numbers, a handheld tuner can be the perfect jumping off point for a high-power build. SCT even offers a teaser trailer set of preinstalled dyno proven performance maps to get you started on your power journey.

We often either forget or neglect the additional steps needed when upgrading power production in trucks. Don't forget, the factory PCM settings are there for the general use of everyone, not just your application. There's going to be strain on other components due to the upgraded power, and you need to pay attention to those changes. Monitor transmission temperature, coolant temperatures voltage, and other critical vehicle statistics with the X4. Same goes for many mechanical changes that benefit from electronic edits.

Another benefit of being able to communicate with your ECM via computer is the versatility of having a basic diagnostic tool with you. Check engine lights coming on in the middle of a weekend cruise or during the workday can be mood killers, not to mention the cost of diagnostics from a shop these days. With the x4, you can scan your own codes and potentially solve your own problem. This could pay for itself a few times over by preventing repair visits.
