Maf sensor code?

[powerstrokenstang]

So my work truck,12 cab chassis, got the p2078? iirc code of mass air flow, man press throttle correlation at higher load code. Replaced mass air flow sensor and came back. Pigtail/ plugin appears to look good. Where do i look next?

What mods? Ive seen dirty air filters and bad egr valves cause this code. If i remember right, a lot of guys were having to get revised tunes with the no limit intakes as well due to the size of the piping.
