Get The Most Out Of Your Truck Every Time You Drive

If you're looking to wake up your 2014 Duramax and make it perform the way it should have from the factory, this Switch-On-The-Fly Tune Pack is the answer. You’re getting five fully custom tunes that you can switch between on the go, without pulling over or plugging in a bulky device. Whether you’re towing a trailer, hauling tools to a job site, or just putting your foot down for fun, there’s a tune built for exactly how you drive. The added horsepower and torque across each level makes your truck feel quicker, more responsive, and easier to control in every situation. The throttle reacts the way you expect it to, shifting is firmer, and the truck just feels alive. Plus, it keeps your emissions equipment intact and meets 49-state legal requirements, so you don’t have to compromise power for compliance. You’re not just tuning your truck, you’re unlocking its full potential with one of the most proven setups on the market.

Custom Tuning That Adjusts With Your Driving Needs

This Switch-On-The-Fly Tune Pack uses DuramaxTuner's deep calibration knowledge to safely modify over 100 parameters from stock for your 2014 LML. Each of the five included tunes is purpose-built, from Optimized Stock for troubleshooting or lending out your truck, to Heavy Tow with SMART EGT control and enhanced throttle calibration for safe trailering. The Street and Sport tunes bring major gains in horsepower and torque, with the Sport tune offering +135 RWHP and +243 ft-lbs for aggressive driving scenarios. Meanwhile, Light Tow blends everyday usability with just enough boost for smaller trailers and weekend hauls. The ability to switch tunes without shutting the truck off means your power delivery is always suited to the task at hand. Combined with the included EFI Live SPADE hardware, this setup is simple to use and ideal for those who want serious performance without sacrificing emissions or reliability.
