Transplanted into a 1972 LeMans. All stock. MAF in a 4" tube. Has really bad idle surge. Ive done some searching on tuning the E78 and am needing some guidance. Thank you in advance.

MAF settings are wrong for speed density tuning.
MAF fail high, set that to 2hz and the low fail to 1hz, then the 3 MAF dtc's to fail on first error.
Is the rest of it stock or does this have a cam in it?
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.
Completely stock engine. I will adjust maf settings and report back. Thanks!
Changed the MAF fail settings and still has same issue. The only issue is the sure while in park or neutral, if its in drive or reverse everything is perfect and it drives normal, just has a terrible surge in p/n.
