MAF Descreen
 

Worth doing on a relatively stock LT1? Any advantage/disadvantage? And what's the best way to do it?

pry it out with a pick or screwdriver CAREFULLY. you dont want to damage the nodes. no big difference but WOULD essentially aloow better air flow. in the long run every little bit counts.

Descreen yes. Port no.

Did it this morning, took it apart just in case. lol. Also did a TB bypass while I was at it. Now THAT was a bitch.

I think the screen is put in to straighten the air at idle
