Question- I just had a superchips racing tuner installed with a DPF delete pipe. Was installed at a shop and I watched as the tuner was programmed. All that came up after downloading the stock settings and setting it to level 3 was the speed limiter setting. When I got home, I looked at the manual and it shows in the advanced features EGR management and DPF management settings. I connected the tuner back up and was unable to get the features to come up. I'm concerned that the engine is still trying to use the DPF with the delete pipe in place. Anyone got the same tuner and can help

any engine codes yet? if not the ECM hasn't even noticed the dpf is gone, there are two egt probes and two pressure sensors in the dpf, and if the ecm doesnt get the readings withing the proper operating limits, it will throw an engine code, and put the truck into limp mode almost instantly

if your truck runs fine i dont think you have anything to worry about :happymugs
