    Question?

    If maf is the precise amount of air and sd is an accurate amount then why would someone delete maf?

    Sd is technically more of an estimation.

    Most delete MAF's when dealing with more aggressive combinations. The overlap and reversion wrecks havoc on cars with MAF's sometimes.

    Some guys delete them because they want as few restrictions in the intake tract as possible. Is there a major power gain? Yes, no, and maybe!
    There are alot of other factors that come into play.

    Then how would you pass inspection if you delete maf. From what I understand the maf codes must be enabled so the pcm will fall into sd. I think I got the cat delete/rear o2s figured out

    It depends on the state, city, county, or parish.

    Texas, Fort Worth, Tarrant county. I asked guy at inspection station and he said I am allowed 1 fault code. He really didn't know anything about maf delete.

    1 more question and I'll leave everyone alone for another couple days.

    GMVE= CYLVOL*VE/R

    what is R
