Everything Your Duramax Should Have Felt Like From Day One

If your 2014 Silverado or Sierra HD feels capable but a little held back, this Five Tune Pack is how you finally unlock what the truck was built to do. The first drive after tuning is usually the moment it clicks, with stronger pull off the line, smoother throttle response, and power that shows up exactly when you ask for it. You can switch between tunes depending on the day, whether that means calm daily driving, confident towing, or enjoying the strongest performance possible while keeping reliability in check. The truck feels lighter on its feet, more responsive in traffic, and noticeably more relaxed when hauling a trailer. What’s more, everything remains emissions intact and compliant in 49 states, so you get real gains without cutting corners. This is the kind of upgrade that makes long drives easier and short trips more fun. It simply makes the truck feel right.

Five Purpose Built Calibrations With Proven Hardware Included

This package includes five custom tunes developed specifically for the 2014 GM 6.6L Duramax LML, along with the EFI Live SPADE AutoCal V3 handheld tuner. Each calibration is built with more than 100 changes from the factory file to improve fueling, timing, throttle mapping, and overall drivability. The Sport and Street tunes deliver strong horsepower and torque gains while maintaining smooth power delivery and factory turbo brake functionality. Light Tow and Heavy Tow options incorporate SMART EGT Control and air fuel ratio limits to manage exhaust temperatures and reduce soot during sustained loads. An Optimized Stock tune is also included for diagnostic use or situations where minimal power change is preferred. All tuning is flashed cleanly through the OBD port with no wiring or sensor modifications required. For trucks with drivetrain changes or towing demands, optional TCM tuning is recommended to fully complement the ECM calibrations and maintain ideal shift behavior.
