Did you ask NAPA who makes the brand MAF they sell?
No I haven't, but I have had huge problems with aftermarket parts. For example, my dads 07 K1500 had a vapor purge valve go bad (tested) and I put an aftermarket one on it, lasted a couple months. Ordered a GM one, no problems since. Dozens of these stories, aftermarket is just terrible!

GM vehicles love GM parts, especially emission and ignition parts. If I substitute it is typically Bosch or Delphi or Denso. So many of GM parts are made by these suppliers.

Delphi produces TWO maf sensors for these trucks

Do not get the cheaper one, thats the equivalent of aftermarket. I have this one ,it works, but build quality is evident so who knows how accurate

The expensive one is the replacement just like the OEM gm
You could also use a junkyard OEM delphi, and clean the sensor
