My guess is detonation due to overboost, not necessarily leaned out, though I will likely get the injectors tested or upgraded before they go back in.

More logging/tuning at lower altitude would have likely avoided/prevented it. You have to be able to collect data, so boost, and wide band are a minimum and a way to log them. So if your ECU doesn't have these sensors and a way to log them, you need smart external ones like the LC-1 and Dephi gauges.

Misfire (It did rethrow a P0302) = Cylinder #2 Oil all over the plug. Compression apparently insufficient to even compress the valve on the gauge.

What is mildly interesting is that this is the same cylinder the TIC guys had problems with the end of last year that I was reading about last night.

I thought it was supposed to be Cylinder #4, Driver side rear, that fails...
