Thread: VE Air -vs- MAF

    VE Air -vs- MAF

    So question. Looking at my tune I always see that when my car is at WOT the MAF is always greater then my VE. Usually by like 10lbs/min.

    Wondering what can I do to make them closer to each other? Is it possible to get them equal? I have noticed in past tunes that when they get closer my butt dyno tells me that its pulling harder. Correct me if I am wrong.

    What adjustments can I make to get them closer if its worth doing so?

    FYI:
    2007 Saturn Sky Redline
    Relocated MAF to cold pipe.
    Fuel Injector constant altered to correct fueling after relocating. If it matters....

    If any info is needed beyond that please let me know and I will do my best to answer.

    Per CBSSOB:

    Usually closer flows more air increasing the ve numbers. Matching helps but dyno could prove otherwise so make a butt dyno file and save it separate.

    What we were talking about was the cams at wot. To move them closer so that the engine flows more and get the VE and MAF to match closer to each other.

    "Closer" referring to the overlap on the cams. so more overlap flows more air thus both lb/min maf & ve go up.
