agreed. also I *think* if the TB was at the root of this, the boost gauge would be fluctuating during the incident.
> Could bypass valve be failing to stay closed.
it does "feel" (and sound) like that. I think the Forge valve came with a few additional springs, Ill see if I can find them.
> Octane+temperature issue? Knock avoidance freaking
> out in hot weather?
I think OpenSID reports on knock sensor, I can check.
> Turbo hose failing at high pressure?
it fits ... Ill look for that in the piping ... intercooler too for that matter.
