IMO, you probably damaged the engine by running all those other mods without putting on EM first. The 04-05s are known to run stoic under boost before onset of Open Loop, after putting on an Uppipe and downpipe+the third cat eliminator, you were probably running lean for far longer than what was programmed by subaru.
The problem didn't show up until you flashed stage 2 which upped the boost on an already damaged engine.
