50% throttle and 100% feel the same, truck has issues getting to 60mph empty.
The delete tune has been on the truck for the majority of its life so I don't believe the problem if from that.
I adjusted overhead as the engine is at 10,000 hours and everything was still within spec from new.

I was sent this persons engine file today. Here is the review...

Its a bad delete. Not sure if it is the programming alone but it is showing silent derate active due to incomplete regen cycles.. and it is able to jump out of non-egr operating modes under certain conditions. this is not good at all. All engine operating mode control logic to prevent the engine from trying to do things like warm up the exhaust system that is now hollowed out, its ability to enter regen modes, to entering SCR and DPf management operations is still active. All the prevention of this, as a requirement of a decent delete file is missing from the program. - It could easily explain some of your symptoms, and it certainly should be your next move to have the programming corrected, so that this can be eliminated from the list of possibilities of your issues.


-- To me, it looked like someone who was poking and prodding blindly at making this delete. They did ok in some places of the programming, but then completely ignored the major stuff that would get the engine in trouble. It seems fairly obvious that whoever made this program did not know half of what they were looking at in there, and ssusmed that the ecm would magically know what to do with itself.. but it in fact is completely unable to 'Auto-correct' for all of those things like missing exhaust components and missing egr gas.
