It is highly suggested to monitor EGT's on Levels 4&5.
Idle Sound: The sound of the exhaust while idling can be changed by commanding the VGT turbo open for the Rumble idle or closed for the Whistle idle.
Low Boost Fueling: Standard Low Boost Fueling is recommended for daily driving and towing. Increased Low boost fueling increases the amount of fuel injected at lower RPM/Boost which results in more low end power.
Shift Points: Standard Shift Points is recommended for fuel economy. Raised shift points hold each gear longer and aids in throttle response and engine/exhaust braking.
