My friend has an 07.5 LMM with a ppe tuner and a 4" exhaust but today we took the exhaust and the ppe tuner off becasue he has to take the truck to the dealer after we finished i turned the truck on and the cel came one i scaned the code and it said p0546(exhaust gas temperature sensor circuit high) i tried to erease the code but no luck has this happend to any one??

 

I'm curious as well. I just bought an 09 LMM and have been trying to decide whether to go with DPF delete or not. Living in California, I would have to be able to reinstall it every once in a while.

 

There is a DPS trooper around New Braunfels that has it out for loud diesels. He got a buddy about a year ago, gave him a defective muffler ticket. I was on a Powerstroke only forum and he had gotten several of those guys too. One of them had a muffler but the trooper said it was hollowed out. One guy even fought the ticket and took it all the way to a trial by jury(he lost). After the trial he watched the trooper get into his private lifted superduty GASSER!!! I don't know if any of these guys are members on here or not. I just lift out of it anytime I go by a DPS around here because they also been checking for cats and dpfs.
