Maf issues/10.2

Hello guys,
I just got my street tune yesterday for the mods below. Everything felt good tuning. Except my budd said my maf was slowly increasing during pulls. it would go up 3 back 1 up to back 1 and so forth. He thinks its a dirty maf sensor? Before stopping we got my afr around 11.8-12.1. Now later that night I took of my hydra shield and went out Driving, mind you it's 33* out. I would go WOT all the way till about 69-7k and then my afr would drop to 10.2-10.9 and make this weird whistling noise, and pull power. Do you guys think that it's going rich bc a dirty maf?, taking off the hydra shield, or cold weather, im going to get a new filter this morning and maf cleaning and see what I can do.

Look to make sure your intake is secure. You could be pulling air from other locations. Look before the sc and after the maf.
