When You Want Your Truck To Hit Hard Every Time

If you're the kind of driver who doesn’t settle for “good enough,” the Sport Tune is built with you in mind. This is the most aggressive tune available for your 2016 Duramax, delivering up to +135 RWHP and +243 ft-lbs of torque.

From firm shifts to eliminating the dreaded dead pedal, this tune delivers the most performance you can legally run in all 50 states. It's the perfect option for guys who want to feel that rush again, whether they're launching off the line or just blowing past the slow lane. And while it's not designed for heavy towing, the Sport Tune is a beast on the road when paired with proper monitoring and supporting mods. If you're chasing maximum power without turning your truck into a science project, this tune gives you the edge without the headache. Just be smart with it and you’ll be blown away by how it wakes up your truck.

Maximum Output Through Safe And Proven Calibration

The DT Sport Tune isn't just about brute strength, it’s built with precision in mind. With over 100+ calibration changes from stock, this custom tune reshapes how your Duramax performs across the board. It holds 50-state legal status while still reaching 532 peak horsepower and 1008 ft-lbs of torque, thanks to emissions-intact design and detailed tuning. Delivered through the included EFI Live AutoCal V3, the setup gives you a simple way to flash and scan your truck as needed. To harness the tune properly, supporting mods like a low-pressure lift pump and transmission tuning are highly recommended. While this tune is fully capable of moving big numbers, it's not meant for constant towing unless you're monitoring your gauges carefully. It's best used as part of a Switch-On-The-Fly package so you can unleash the power when it makes sense and rein it in when it doesn’t. Designed by the experts at DuramaxTuner, it's a performance tool with technical backing you can trust.
