2004.5 LLY EGR Block???'s
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...

GAMEOVER,
First off, I am new to all this too, but...
Give this a try. Go to {B1506} EGR Maximum Percentage and {B1507} EGR Minimum Percentage and set all the values on the chart to zero. That may clear up your setting of codes.

Well I tried the settings above and now it will only Boost to 8-9lbs maximum and EGT's are over 800F...No DTC's or codes

ok heres my problem....the truck revs up and maxs out at like 8-9 turbo psi but my egts are out the roof....truck ran fine till i installed an egr delete kit.....truck feels like its in limp mode but i have one code on start up 101 maf...
You will not see a EGR code because you disabled the diagnostic code with C2401.
I wonder if you may have a leak somewhere on your delete kit. Double check the up-pipes and the intake caps. I would say there is a leak on the intake side.
