    Custom OS on Mass Air FLow

    I know 2 & 3 bar custom OS that can be bought.

    But can a custom air flow Hz be bought that goes pass 11.500 Hz on the Mass Air Flow area?

    Most people will just get a different throttle body and MAF sensor to deal with that.

    Atleast anyone with a 3800 motor.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Just a question to keep a open mind open.

    Is that a yes or no on my question?

    Or may light be shined to my question in case someone ask me, I like to be able to support HP tuners if I'm ask this question out side this site. Cause there are people that still never heard of HP Tuners. At least from what I'm running in to.

    Buy a 2cent resistor and solder it on the maf, or buy a mini afc.

    For the most part no. There are a few E38/E67 custom operating systems that extend the maf table but thats the extent of it.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    x2 on bigger TB, use a larger diameter pipe (4") and a differant MAF and rescale accordingly.

    The larger pipe is the key, as the same amount of air flowing in the larger pipe will flow slower, which will make the MAF read slower. This will require adding more fuel, as the engine thinks its getting less air and its actually getting the same amount of air, just at a slower speed over the MAF.

    This one is pretty user friendly if you go the mini route...

    I say bigger tube and a new MAF is the way to go, but if you want the mini that is the one to use imo
