so i'm finding that HPT is not writing to the processor says it is but after I upload the tune then read the vcm I see none of my changes
Check your grounds. When you did the swap dis you accidentally cut any of the wires that were strapped to the back of the cylinder head? You should have dash lights regardless unless it's in Stealth Mode.
Push and hold the two brightness buttons for the dash for three seconds and see if your tach starts working.
Or try pushing in on the scroll button while starting the car to see if you can get it into engineering mode.
Still nothing, check the front lead wires to the block.

so did anyone ever figure this out? I am having a similar issue however my dash is fine.
Attached is the current tune on the truck. is there something that needs to be done to the harness that is now not being used for the old dod valley cover?
Looking for an update as well. I'm experiencing a similar problem with an E40 PCM from a 2006 GMC Envoy XL 5.3L.

The 2008 Sierra that I replied to does. You need to set all DoD codes to no error reported, uncheck the SES box, and change the DoD to disabled.
