MAP should read 100-103ish kpa with the key on engine off. Your's is reading 134kpa, inspect the wiring.
Install the factory MAP and settings if you want to, just a trial to see if it runs. It's not uncommon to get bad new MAP sensors.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
VATS issue will start and die if tripped. No fuel will do the same thing, make sure you have pressure.
I did have a passlock code p1631 stored but took care of that. i will look at the map issue next. thanks, Andy
