Im new to HP tuners so Im not sure exactly what im looking at, but perhaps someone could see something that I cant. The car sputters and dies at what seems to be random times. If you need any more info let me know. The fuel pressure is solid I put a gauge on to test that.

Something is wrong with your MAP sensor, it never changes from 83 kpa in that whole log. Because it's stuck so high up, it's causing fueling problems for sure.
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.
That did the trick. I seen that it never moved but didn't know if that was normal. Thank you for your help.
