I have a 2008 Duramax LMM, I just installed the PPE Race Program with the DPF delete and put a 4" turbo back exhaust on this weekend. The truck runs good but I have a CEL with the trouble code 2455 that won't go away no matter how many time I try to clear it. I spoke with PPE and they are not sure of what this code is and what it means. All the plugs are greased and sealed up with electrical tape so no moister has gotten in the sensors. Any Ideas at this point would be a great help.

answered it in your other thread.

How's the EFI Live working for you?

perfectly. I wouldn't do it any other way, because you can fix the issues you're having yourself. Whichever tuner you buy it from will supply at least one good tune tailored to what you want, and you can tweak it from there. I've done the locked tune deal in the past on other vehicles, I prefer to be able to make changes on my own. There are also tune libraries with several tunes available to play with.
