Somehow in my bumbling key punching I have lost my cruise control. I am not sure if it has to do with tuning or if something is wrong with the truck. Is there a place to turn it on and off with EFI live?

Not really, the only table I am aware of is B0852 max. injected fuel in cruise mode.
2005 RCSB 2500HD GMC Sierra DURAMAX LLY
1955 Chevy Truck 1st series, being restored
2002 Mercedes C270 CDI
Before flashing, did you save a copy of the ECM's tune...?
Just to update the thread in case it happens to anyone else, I had loaded a manual trans file into my auto truck so the ecm and tcm were not communicating. Amazingly the truck ran and shifted fine other than the cruise problem.
General rule of thumb, ALWAYS use the .tun file read from the truck, switching tunes from one truck to another tends to result in tears.
