This is after trying 2 different MAP sensors (ZR1 3 bar), checking the wiring to the sensor, replacing the wiring from the ECU to the sensor, and even tried 2 different ECU's (Both P59's with 3 bar SD OS).
Anyone have any idea what this could be??

You can also turn the key off and it does the same oscillation for another 20-30 seconds.
Random question, how many MAP channels are you logging?
Just the 3 bar channel or several map channels?
Does removing the channel, then re-polling for supported parameters, then adding the channel back in help any?
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.
Fairly certain I'm only logging the one MAP channel.
Haven't tried removing the channel.
I had the exact same thing when I had a 1Bar map and 2Bar map graphing.
