2023-2025 3.0L LZ0 Tuning is FINALLY here !
!!!!Before reading any further - Ensure you have a LZ0 and not an LM2 refresh prior to ordering!!!!
Increase power output from 0-55RWHP on your 2023-2025 Sierra / Silverado with the usage of our proprietary custom tuning solutions tuning solutions.
This is a long LONG time coming! GM Sierra and Silverado owners 2023-2025 equipped with the GM LZ0 Duramax 3.0L engines are now available for power uprating! These trucks are equipped with the Global C GM E66 ECMs. To tune either of these controller we have to unlock the security from them. Once this is completed, they are ready for custom tuning.
Since we own several of these trucks we have seen regeneration frequencies stay around 300-400 miles between regenration time periods. Our goal is to keep the regenerations under higher power levels above factory time periods by running the ECM at higher AIR/Fuel ratios at all times, and leverage the intercooler to reject the slight increase in heat from elevated boost levels.
What the user will see as a result of our calibrations are:
- Increased throttle responsiveness (reduced or eliminated deadpedal)
- Nearly the same or similar to OEM diesel exhaust fluid consumption (DEF)
- Increased time between DPF regenerations
- Increased torque in all power levels which allow TCM to command the next higher gear (fuel savings)
- Increased fuel economy (average increase depends on driver habbits)
- Quicker transient response times to degraded air/fuel conditions
- Enhanced and more conservative engine backdowns from sustained high EGT conditions
- Enhanced and more conservative timing control during high load conditions (towing)
- Removal of the top speed limiter
- Removal of autostart stop functions
- Tire size changes
- Overall better drivability and end user experience
Selectable Power Levels :
+20HP +45 FT/LBS ~ Optimized Stock/Tow tune
- This tune represents the maximum possible fuel economy under all driving scenerios with. With over 130 calibration changes involved the refinements to the factory calibration data will extend time to regeneration of the DPF, and increase responsiveness of the truck with a slight increase in total power output while maintaining OEM DEF consumption.
+30HP +70 FT/LBS ~ Daily Driver/Sreet tune
- This tune represents the maximum possibe power output availible during MAXIMUM GVWR towing scenerios. All factory backdowns and derates are utililized to keep the truck in its safe zone for heat rejection. With over 266 calibration changes involved the refinements to the factory calibration data, and increase responsiveness of the truck via removal of the dead pedal feel while keeping the truck at better than OEM level fuel economy.
+55HP +120 FT/LBS Max Effort !! (Aftermarket Cold air intake required) !!
- This tune represents the maximum possibe power output availible with the factory turbo charger and air intake system. All factory backdowns and derates are utililized to keep the truck in its safe zone for heat rejection. With over 387 calibration changes involved the refinements to the factory calibration data this will increase responsiveness of the truck via removal of the dead pedal feel. Even though the truck will back itself down once heat rejection reaches a maximum it is not advisable to tow with this calibration file loaded. Aftermarket intake (S&B) is required to safely push these trucks over 60HP due to the restriction the factory intake presents.
LZ0 Transmission Tuning (T93) :
- Currently we CAN NOT unlock and support this controller
What is required for ECM tuning ?
- ECM unlock through us – ECM get sent off to HP Tuners for unlocking (this is required)
- HP Tuners MVPI3
- 6 License credits
- Tune file purchase
!!This calibration package can only be installed using the HP Tuners MVPI3!! As such the end user MUST have either an unlocked/upgraded ECM (E66) from HP tuners or from VSE directly and also MUST either purchase licensing credits and MVPI3 already have them in their possession.
