Wake Up Your Duramax With Street Driven Power That Feels Effortless

If you have ever felt like your 2016 Silverado or Sierra 2500HD or 3500HD LML had more to give, this Street Tune is the upgrade that finally unlocks it. Right out of the gate, you are looking at gains of up to 110 rear wheel horsepower and 198 lb-ft of torque, and you can feel it the first time you roll into the throttle. The truck accelerates harder, the dead pedal feeling disappears, and it honestly feels lighter on its feet pulling onto the highway. What makes this tune stand out is that it keeps your emissions equipment intact and remains 50 State Legal under CARB E.O. D-845, so you are not trading peace of mind for performance. The power delivery is smooth and predictable, which makes daily driving more enjoyable instead of overwhelming. Additionally, the factory turbo brake function stays fully operational, so you keep the control you rely on. It is the kind of tune that makes you look for excuses to take the long way home while still maintaining OEM levels of reliability.

Advanced Calibration And EFI Live Control Built For Real World Performance

Under the hood, this Street Tune is far more than a basic plug in upgrade. It includes the SPADE device, also known as the EFI Live AutoCal V3, which gives you simple handheld OBD flashing along with scan tool capability for logging engine data and troubleshooting. The calibration itself features more than 100 changes from stock, carefully designed to increase power while reducing soot compared to typical box programmers. Furthermore, there is no wire splicing or tampering with fuel system or turbo sensors, which keeps the installation clean and the factory systems protected. The wider torque curve improves drivability across the RPM range and works especially well with common bolt on upgrades. For trucks that see occasional towing under 8000 pounds or mostly highway use, the added torque makes passing and merging far more confident. Pairing this with recommended transmission tuning helps optimize shift strategy and torque converter lockup, ensuring the extra power is delivered smoothly and efficiently to the ground.
