So I have installed the zr1 map sensor and changed the configuration to Linear = 312.5 and Offset = -11.25. Now its running very poorly and i cannot even tune my car. Am I missing something? I have attached my log file and tune file.

I'm on my phone so I can't open the file, but are your units correct in the tune (should be kPa).
Ummm, Is it a genuine GM sensor?
2000 Camaro SS 2015 L83 port injected, Whipple 3.0, 4L80E, 8.8 Ford
2013 Silverado 5.3, 6L80k 8.8
Probably a bad MAP.
Your key on engine off KPA readings are 229kpa, just sitting there. Should be right around 100kpa if you live at sea level.
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.

No, you only have to change the linear and offset settings to make the MAP work.
I don't know what your other problems are. Changing just the MAP sensor itself won't cause this issue. You should probably double check that you don't have to swap pins around in the connector to make the ZL1 map sensor work.
