GMS Maf I think uses different resistors to force a lower airflow that actually happens, this means less fuel, which leans out the stock rich state.
But if you are tuning as stated here, you can tune SD then reconnect MAF and adjust maf table based on the % error over your known good SD tune.
Bottom line, tuned MAF table.
