I just want to get it with the PDA to be able to monitor all of my trucks parameters. I never intend to use the added power and only have to have the ottomind in order to make the PDA functions. What do you guys think... . is there ANY way I could do any damage to the truck? When using level 0 is there any stock parameters changed that could affect the truck in a negative way? My Cummins is new... ... . so I am not taking any chances.
