I have a 2000 M6 SS...I took out my stock airfilter ( I have about 18k miles)...and it was almost completely black and had two bugs in it....could this have affected a dyno run? Maybe I was running rich because there wasn't enough air getting through?

 

It all depends, its always good to check when ever you can...I would reccomend getting a K&N filter or Holley, it sounds like you live in a dirty/dusty area.

Yes.

Negatively.
