Yet another stinking MAF question...

Hi guys, yeah it's me again. I have to tap into your knowledge banks for a sanity check here. I created a MAP in live so I could log DYNAIR vs. MAF FREQ. I drove around so as to fill as many cells as possible. When I compared what I logged against the stock Z06 MAF table, I noticed some cells with as much as a 50% increase in air volume! I couldn't believe it. All this BTW, is with my LTFT's zeroed.

What I'm wondering is, is this normal for a H/C car and a free flowing filter? Sure seems like a lot to me, but since I'm new to this I figure I'd ask the experts.

I'm no expert, just tooling around...

If your IFR table is correct, and
if you already dialed in your VE table in SD,
then you have just created your new MAF table.

If you have a wideband, make the MAP so it is AFR vs Freq.
