Smart Adjustments Without Sacrificing Factory Functionality

The Optimized Stock Tune is a precision calibration built for 2016 Silverado and Sierra HD trucks with the 6.6L Duramax LML. While it doesn’t raise peak power, it makes subtle improvements across more than 100 stock parameters to improve throttle feel, lower soot output, and enhance overall efficiency. It’s ideal for trucks running slight modifications, like aftermarket intakes or updated tire sizes, where tuning is required but added horsepower is not the goal. This tune also helps troubleshoot physical issues or drivability concerns by maintaining stock power levels while improving system behavior. It’s fully emissions compliant and CARB approved under EO# D-845, making it safe to run in all 50 states. The included EFI Live SPADE hardware offers complete control over your truck’s programming, from data logging to diagnostic scanning. For those who want better drivability or are planning to add transmission tuning, this calibration lays a solid and reliable foundation without pushing your truck too hard.
