A friend of mine has a lmm with a banks exhaust and one of my milage tunes. He's getting like 8 mpg so he wanted to install a exhaust to get rid of the DPF. I keep getting a P0546 and a P2033 code. If I shut those MIL's off they shouldn't pop back up right? What do you guys usually do when tuning for no DPF and EGR? I went into those two parameters and disabled them. I went through all the mils and shut off anything that had to do with EGR and DPF but hadn't re tuned the truck yet. Just wanting to make sure the CES light won't come back on before I re tune the truck. Thanks, Eric
