What would cause a surging idle? I installed a MSD2313 3 bar map. Would this issue come from installing a 3 bar vs the stock 1 bar? Anyone have a part number for a LS 3 bar map?

Did you change the linear and offset settings for the MAP sensor?
Is this for a boost setup and is the rest of the tune going to be for boost?
Post the tune as well.
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.
