detonation/pinging??

I noticed today that under WOT, I can hear pinging in the engine. After reading about detonation, I think this is what it is.

I installed a GHL header and B&B exhaust, and running .9 bar boost... Would that be detonation? I'm about to put the car away for the winter and was going to take it to the dyno in the spring to check the A/F mixture and make sure it is tuned as optimally as possible.

Is that detonation.. ? Should I reduce the boost? Could it be the gas I run (91 octane)?
