Unlock The Power Your Duramax Was Built To Handle

If you’re the kind of driver who’s always wanted to feel what your LML Duramax is truly capable of, this Sport Tune is the one to get. It gives you the biggest rush we can legally deliver while keeping your emissions equipment fully intact. With up to 135 extra horsepower and 243 ft-lbs of torque, your truck will launch harder, shift firmer, and respond quicker than it ever has before. There’s no dead pedal feeling, and every bit of added power feels clean and usable. This is perfect for daily drivers who want more excitement or for truck owners planning future performance upgrades. If you're tired of your truck feeling sluggish or simply want to enjoy the ride, this tune brings the fun back into every mile. Just be smart with it, this level of power isn’t for the inexperienced, and monitoring things like EGTs while towing is a must. But when used responsibly, it’s an absolute game-changer.

Engineered For Maximum Output Without Compromise

The DuramaxTuner Sport Tune is built from the ground up with performance and precision in mind. Every calibration includes over 100 changes from stock, dialing in throttle response, fuel delivery, torque management, and shift points. The result is a powerful and predictable driving experience that adds performance without sacrificing reliability. This tune pushes your LML to a total of 532 HP and 1008 ft-lbs of torque, all while keeping emissions systems untouched and functioning. It’s 49 State Legal and includes EFI Live’s AutoCal V3 SPADE, giving you a proven platform for diagnostics and flashing. No wire tapping or sensor hacking required, just smart, effective tuning that brings your truck to life. For best results, especially under heavy use, supporting mods like a low-pressure lift pump or transmission tuning are strongly recommended. This tune is ideal for performance enthusiasts who want control, consistency, and serious gains without cutting corners.
