Let Your LML Breathe With Tunes That Work Every Day

If your 2013 Duramax feels like it's being held back, this 50 State Legal Five Tune Pack is the key to unlocking its full potential without crossing any lines. It delivers noticeable gains in throttle response, power, and drivability while keeping your emissions equipment intact and compliant in all 50 states. Whether you're towing a heavy trailer, heading out for the weekend, or just want more fun on your daily drive, each tune is designed to give you exactly what you need. With options ranging from heavy tow to sport, you’ll finally feel like the truck is responding the way it should have from the factory. Backroads feel more responsive, loaded hills feel lighter, and merging onto the highway takes far less effort. The power is clean, the shifts feel smooth, and the factory turbo brake continues to work like normal. Best of all, you can count on reliable support from a tuning team that knows the platform inside and out.

Five Calibrations Tailored For Power Safety And Versatility

This five tune pack is built for the 2013 GM 6.6L LML Duramax and provides a wide range of performance options using emissions intact calibrations that are 50 state legal under CARB E.O. No. D-845. The included tunes cover everything from Optimized Stock for troubleshooting or valet situations, to Heavy Tow and Sport for when your truck needs to work harder or move quicker. Each calibration is built using over 100 changes from the factory file to improve timing, boost control, fueling, pedal response, and soot management. The Street and Light Tow tunes are excellent for daily use, providing smooth acceleration, better shift points, and improved trailer control without overloading the driveline. All tunes retain the factory turbo braking feature and use SMART EGT Control to keep exhaust temps in check during extended pulls. This tune pack requires the EFI Live SPADE AutoCal V3 device for installation and works through the OBD port without the need for spliced wires or modified sensors. For trucks with larger tires or upgraded driveline components, optional TCM tuning is recommended to maintain consistent shift quality and match the added torque.
