Looking to see what I need for the software side of things to delete the dpf and egr and swirl flaps(no issues yet) on my old r320 I use on my farm the extra torque and fuel economy would be nice. I have no problem doing the hardware side of things just my scan tool doesn't allow me to delete sensors or change values that deep. I know it can be done this way I just don't know what tool to buy. My egr keeps acting up putting it in limp mode but then frees up once warmed up and drives fine. No real oil burning and dpf is not clogged at all just wanting to see what options are out there. No bluetec nonsense on this model.
