Sorry for the confusion.

By chirp, I meant between shifts. From a dead stop, all you have to do is mash the throttle on a RWD. You don't even need to brake torque on the stock tires.

Warmed RE050a's might need a little braking

fwiw, sti's have a much better power to weight ratio to start and still don't chirp on shifts until you're pushing over 400whp. a heavy auto car with considerably less torque is *never* going to do it regardless of how you program the auto's control system.

Actually, this one I disagree with - the issue is with the torque converter (and the OP's AWD traction), not the amount of HP. If an auto had the normal amount of BHP, but a clutch that you could disengage then slam together mechanically (i.e. normal clutch), it would chirp 1 - 2. The auto doesn't because the torque converter doesn't bang together like a clutch.

I saw an '06 MT sedan (less HP and TQ than my '07) chirp the tires from 1 - 2nd in front of me.

BTW, who cares if the tires chirp from 1 - 2?? I care how my car drives...

Chirp = loss fo power aka imprecise shifting...

my s2k won't chirp 1-2 too uncool.

^+1 i have chirped an X before, it was the loaner i got from the dealer and i was beating the hell out if it. i was on a turn, not a sharp turn, but a turn sharp enuf to pull a little Gs at ~30mph. the car was in DS mode and my foot was in it.
VDC was ON. snow mode was off.

the car got loose in the back end and VDC kicked in right away. took me off guard. i was really impressed to tell you the truth.

you can do it, in the right conditions.

Some of you guys need to get over yourselves.
That was the politically correct version of what I want to say too.

Infiniti does not make a performance car.
That doesn't mean I don't want my sedan to perform up to it's potential.

there isn't much potential left in it, though.

I have an AT. I too have "chirpped" my wheels going from 1st to 2nd gear. Not really hard to do no matter if you have an AT or MT.
