Should I be concerned that I have a tuned 2009 LMM duramax with a locked tune and the DPF re-installed?
The logic I seem to understand is that the computer won't regen and hence I could end up with a plugged DPF and a dead motor. See as I don't have the original tune I can't read and re-enable the DPF regen and codes for the computer. I live in an emission compliant area and running without the emission equipment will give me a failure.
