This Tune Delivers The Power You Have Been Missing

Acceleration becomes immediate, the pedal response is crisp, and your truck pulls hard with every press of your foot. It’s the most power you can legally add while keeping your emissions equipment intact and staying 50-state legal. Whether you’re merging onto the highway or just want to have more fun on your daily drive, this tune transforms the way your truck behaves. It also eliminates that frustrating dead pedal feel and replaces it with a throttle response that reacts exactly how you want it to. And the best part? You still retain all the convenience of your factory turbo braking and drivability for everyday use.

Built With Precision To Handle Serious Performance Demands

This Sport Tune is more than just a power bump, it’s a complete recalibration of your truck’s performance profile. With over 100 changes from stock, DuramaxTuner’s custom ECM tuning is carefully engineered to maximize power while keeping the engine running clean and reliable. You get all the gains without having to hack into sensors or wiring, and the tune is loaded easily using the included EFI Live AutoCal V3 SPADE handheld device. This tool not only flashes the tune but also allows you to log data, scan codes, and update calibrations as needed. The tune is specifically built to work in sync with factory emissions systems and is 50-state legal under CARB EO D-845. It is ideal for drivers who want aggressive performance without sacrificing compliance or long-term drivability. For best results, it’s recommended to pair this tune with proper transmission tuning to handle the increased torque and shifting demands under load.
