uses a pre-loaded Mini Maxx V1 tuner
Important safety measure: Strongly recommended to use a 10-amp constant battery charger connected to the battery to prevent damage to the PCU due to insufficient voltage during the tuning process
Set the switch on the OBD port to “battery” mode to ensure the tuner doesn’t lose power when the ignition is turned off during the adjustment process
Tune First, Then Remove: It’s essential to make software adjustments using the Mini Maxx tuner before performing any physical deletion
Follow the instructions displayed on the tuner screen, including turning the ignition switch off and on when prompted
If you encounter “initializing communication” issues, try pressing the back button to resolve
Select the “removed emissions systems” options (EGR/DPF/DEF) on the tuner
After tuning is complete, start the engine and check for error codes
After tuning is complete, disconnect the EGR sensor connections
Remove the DPF and install a straight-through exhaust pipe
Plan subsequent removal of the EGR and installation of blocking plates
Sequence is crucial: Removing sensors before tuning may result in permanent error codes
To fully benefit from the tuning, you’ll eventually need to completely remove the EGR system and seal it with blocking plates
