Noob. Maf tuning.

[Nastruck]

04 Silverado LQ4/243 228r 112lsa.

Little confused on tuning the MAF. I zero-d the maf so it would fail and tuned my Ve tables a good bit. Truck runs
pretty good in SD close loop and Open loop. Little more smoother surging in open loop.
Maf idles rough and not real smooth down low. I read a bunch of threads and still confused on a few things.
I made Histogram of the MAF (HZ) vs STFT. And added PIDS - MAF (SAE) LB/MIN, MAF HZ, And Dynamic Airflow LB/min


So as long as my LTFT is dialed in SD then I need to Match the Histogram of my MAF HZ vs STFT back down to Zero?
In order to do this I need to disable LTFT?


The difference in MAF and Dynamic Airflow doesn't quite match the Histrogram sTFT. Is this due to the LTFT currently
enabled?

I read that the MAF should match the Dynamic airflow. Correct?

When you are trying to tune your MAF are you disabling the VE system? You do this by making this change:
