38k miles, no chirps on E10 California 91 of various brands (mostly arco due to price and convenience).

In traffic this morning was next to a silver FR-S and I could hear his chirping with my windows down and light music, I had almost forgotten what they sounded like as it's been nearly 2 years and 30k miles since I've heard them get angry.

I'm of the opinion it goes away as the fuel pump wears in, no need for any additives or blood sacrifices.

Edit: I wish I could change my vote in the poll...
