New from Superchips – redesigned tuning support for the 2011-16 LML engine. The new approach has allowed Superchips’ programmers to get another 135 horsepower and 245 lb-ft of torque to the tires. See more details below.

Official Release:

The LML Duramax is an industry-leading workhorse with great power and torque right from the factory, but that doesn’t mean that it isn’t capable of more.  Our calibrators went to work and redesigned our LML tuning from the ground up to make it better in every way.  The Flashpaq now features up to 135 HP and 240 LB-FT of torque over stock to the tires!  All tuning is 50 State legal through 2015, with 2016 coverage in the application process and pending.

The new LML tuning coverage for 2011-2015 is supported by EO# D-330-18.  Now you can enhance your ride with a low cost, high quality solution with fantastic tuning via Flashpaq PN 2845 and 4845. Learn more about this exciting coverage here.
