All factory backdowns and derates are utililized to keep the truck in its safe zone for heat rejection. This tune represents the maximum possibe power output availible with the factory turbo charger and air intake system.+50HP +110 FT/LBS Max Effort !! (Aftermarket Cold air intake required) !! With over 215 calibration changes involved the refinements to the factory calibration data will extend time to regeneration of the DPF, and increase responsiveness of the truck via removal of the dead pedal feel while keeping the truck at normal DEF consumption while towing. This tune represents the maximum possibe power output availible during MAXIMUM GVWR towing scenerios.+30HP +70 FT/LBS ~ Daily Driver/Sreet tune 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. This tune represents the maximum possible fuel economy under all driving scenerios with.+20HP +45 FT/LBS ~ Optimized Stock/Tow tune Overall better drivability and end user experience.Enhanced and more conservative timing control during high load conditions (towing).Enhanced and more conservative engine backdowns from sustained high EGT conditions.Quicker transient response times to degraded air/fuel conditions.Increased fuel economy (average increase depends on driver habbits).Increased time between DPF regenerations.Increased torque in all power levels which allow TCM to command the next higher gear (fuel savings).Reduced EGR flow into the engine during normal operation without affect on emmissions NOx output.Nearly the same or similar to OEM diesel exhaust fluid consumption (DEF).Increased throttle responsiveness (reduced or eliminated deadpedal).What the user will see as a result of our calibrations are: 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. Since we own several of these trucks we have seen regeneration frequencys stay around 300-400 miles between regenration time periods. Once this is completed, they are ready for custom tuning. To tune either of these controllers we have to unlock the security from them. This is a long LONG time coming! GM Sierra and Silverado owners 2020-2022 (non interior refresh) equipped with the GM LM2 Duramax 3.0L engines are now availble for power uprating! These trucks are equipped with the GM E46 ECM and GM T93 TCM. Increase power output from 0-50RWHP on your 2020-2022 LM2 (non Refresh) Sierra / Silverado with the usage of our prorietary custom tuning solutions tuning solutions.
