This Tune Brings Out The Beast In Your Duramax

If you’ve been itching to feel what your truck is truly capable of, the Sport Tune with EFI Live SPADE is the upgrade you’ve been waiting for. It’s designed for the driver who isn’t satisfied with stock and wants the hardest-hitting, most exciting version of their 2012 Duramax. With gains up to 135 HP and 243 ft-lbs of torque, you’ll instantly feel the difference every time you press the pedal. Acceleration sharpens, shifting gets firmer, and the dead pedal feel is gone for good. Whether you’re carving through backroads or pulling hard onto the highway, this tune gives your truck the edge it deserves. And since it’s 50-state legal with emissions equipment intact, you don’t have to compromise compliance for performance. Just be ready for the thrill, this is the biggest legal adrenaline rush we offer, and once you drive with it, there’s no going back.

Built With Smart Tuning That Maximizes Performance Safely

Behind the wheel, this tune might feel wild, but under the hood it’s all about precision. The Sport Tune includes more than 100 calibration changes from stock, crafted to safely push the limits without risking your truck’s health. The included EFI Live SPADE AutoCal V3 makes flashing simple and secure, and also doubles as a diagnostic tool when you need to scan or log data. Power is delivered with less soot than your average box tuner, and there’s no need to splice wires or mess with turbo sensors. Supporting modifications are recommended for long-term reliability, especially if this tune will be used frequently. For trucks with larger tires or modified transmissions, optional TCM tuning helps keep everything running smooth and in the right rev range. This tune is smart where it counts and aggressive where it matters, giving you controlled performance in a proven, emissions-friendly package.
