maybe put factory programming back in it and fix its issues first. Get it running well again. ... then, for old engines like that prior to 2007, seek out forum member 'running rough' to have a proper de-mandate program made for it again. He is set up to do the really old (pre 2007 era) stuffs around here.

Thanks for your reply rawze the king! , got here from one of your youtube video, forgot to say that the truck is fully egr deleted blocked, yeah its a 2005 ism cm875, i saw you do programming i think? May i extract my tune from the ecm and you look at it ? I think the ecm egr delete was not done properly, bought the truck 2 years ago and issues started 2 months ago with bad injector and then all this followed up. I know my engine is over fueling at around 1300rpm because egt going up and boost going down for a bit then goes back to normal, then there is still that egr temp sensor check engine... do you know if egr pressure sensor still need to be running in my setup, found the egr pressure sensor metal tube to be loose on the manifold threads, and i would need to tap that fitting bigger since the threads are gone
Appreciated help sir!
