Issues with MAF and boost
Just wanted to see who all is successfully using a MAF with boost. I'm I'm having issues with my truck starting off rich at the beginning of a pull and then being lean at the end of a pull because my MAF hertz is reading 13500 at 5500 rpm and by 6300 it's still around 13500 hertz so it's not getting anymore fuel with more rpm. It's a 2011 GMC with a trick turbo stage III

Launching!
I see how it just hovers around 13500 hz. in your log 5000rpm to 6192, try raising MAF fail HZ. to 16000, as well as maf correlation to 8000 rpm, and codes p101, 106 and 121 to 256F and 257f
