Detonation source: Brisk GOR-17
Well, it appears that my Brisk was kicking my butt this whole time. I was chasing my tail regarding the strange source of my observed detonation irregardless of timing or A/F ratio.

Can you identify which hole is the traditional "lean" hole?

It looks like the Brisk plugs are the wrong heat range for our motors as cross referenced.
BTW; the last hole on the drivers side is the most commonly lean hole. Probably followed closely by the second to last hole on the drivers side.

Weren't these things all the rage like three months ago...I could've sworn they were being touted as the wonder plugs.

That's why I suggested checking your plugs. Here's what mine did first trip down the track a few weeks ago..... 14lbs of boost and 40 degrees temp outside. melted 4 of them

Both times I had a plug issue, it was the 3rd back DS on both ocassions, along with the 4th back on 1 of those ocassions.
Of course it's always the two hardest Plugs (@$%)@$@_$^@)$%
Love the design of these Brisk Plugs, but it does seem some are having issues with them ??? Glad to hear the TR-6's got you back to normal Master Of Pain

One thing you need to do also is run a compression check now that you melted plugs. I melted 4 plugs on the dyno a couple of months ago and when I removed No. 8 plug there was a tad bit of alum on the thread. When I went to put the plug back in it spun the threads. I pulled the heads only to find out that the lobes where the spark plug comes threw was melted half way.
Detonation causes the electrode to melt in most cases then the spark seeks the path of least resistance.
Also remember that the piece of electrode that burned off has to go somewhere, right! Mine went between the piston and the cylinder wall.
