The only mass airflow sensor mod anybody should do is check to make sure you have the better GM one, then replace it with a good GM one if needed.

As has been discussed several times, you can check by looking at the stamped identification number/letters on the sensor body. You want a letter followed by two numbers, of any combination.
There's a picture and close-up of the spot in the second picture here:
And even then, for most people, it won't make much of a difference, unless you have a Vararam, supercharger, or a custom tune.

Other than that, keep it stock!
