Got autocal from motorops last week. Installed dsp5 and tunes last night. Seams my dsp switch isn't working so I go to data section I believe to read voltages of switch. Got a code also so I go to read tune and another code. Truck runs fine with dpf removed, or so it seams to so far. What can I do or what can I do?
