I've always said that chirping tires is more of an indicator of how crappy/worn your tires are and not how much power you were making.
My stock goodyears were a perfect example.
When the car was new, i could chirp 2nd gear and that was it (car is a 5-spd)
Around 15K miles, i discovered i could now chirp 3rd gear.
At around 36K miles...when i replaced them due to wear...i could chirp 4th gear.
I put nice sticky Bridgestone potenza S-03's on. These tires are like glue. I could NOT chirp 2nd gear anymore...at all. Beleive me i tried.
Now they have about 30K miles on them, and i can now chirp 2nd and sometimes get 3rd to chirp.
My car is bone stock..has always been stock.
