How can I tell if higher boost is causing knocking?

I'm using an MBC on my '91 9000T and it seems that my overboost fuel cutoff is nonexistent with a stock ECU (I have read 20psi on the boost gage and have even seen it spike to 25psi with no drama). I generally keep the MBC set to max out at 15psi and settle down to 12psi. I figure that this is well within the margin of safety.
HOWEVER...I would love to set it higher but I am afraid that I could be doing damage and never know it until it was too late.
Is there any way to tell?
