    Swapping to 2bar Custom OS

    Good afternoon everyone..

    First and foremost... I did a search and meandered through the first 2 pages to no avail. Maybe the answer is obvious?

    As my title suggests, I've swapped my os to a HPT custom 2 bar. At this point do I fail the MAF? When I upgraded I just automatically assumed that the MAF frequency table would just disappear into thin air (noob thinking).

    Are there any friendly write ups for this upgrade? Things to look out for? I have a few years experience under my belt tuning MAF/VE gen III stuff and some virtual VE, but SD is completely new to me.

    Any help would be greatly appreciated.

    Yes, you must disable the MAF in the tune still if you are going straight speed density.

    Set the MAF fail high to 0hz and the 3 MAF dtc's to fail on first error.
    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.
