Tracing high tension leak/short without dyno

[MrStabby]

Car runs fine until it gets some boost then I get what sounds like a high tension short. I've got LS2 coils and use the factory boots. Has worked fine in the past. I've replaced plugs, cleaned surfaces etc. Other than getting into a dark dyno room, is there some other way to find which coil is shorting? Maybe dust the area fingerprint style, then look for burnt dust?

Buy new coil, HT lead and boots and swap known good item in with each coil sequentially each time you take it for a drive.

Somewhere between drive 1 and 6 should have been able to isolate the issue further.

Continue troubleshooting as necessary.
