Did a EGR Delete kit on a 2004.5 LLY and with EFI Live turned off the DTC's P0401 thru P0406 & P1404 but truck goes into a kind of Limp Mode(no power 1-2lbs of Boost only) after a couple of minutes of driving. Is there anything else that has to be turned off or disabled. Diesel newbie
Thanks in advance...
