    2017 gmc 6.2 failing MAF for SD tuning

    Ive tried failing the maf so i can sd tune the truck but it seems its still using it because no matter what i do to the VVE table the fuel trims stay the same. Any help would be appreciated.

    Post the stock tune and the tune you're using for speed density
