STi Pinging?

Hi STi owners. Have any of you experienced pinging? I'm in the market for one and might be getting one this month. I've heard a detailed discussion on NASIOC about pinging with pump gas. Here's the link:

Some people mix their gas but I think that's a pain. So, I'm wondering if you have heard pinging from your STi and does the ECU retard the timing? What octane and brand of gas do you use. Here in California we have to settle with 91.

Thanks for any input.

No pinging (I am using 93 Octane). I have 500 miles on my car and have had it up to about 5K RPMs

I think the best question is how do I know if I am pinging. How can the untrained driver tell if he has pinging/detonation. I'm going to ask over on nasioc as well.
