You prob. dropped a valve and all hell broke loose...

Dropped valve in the worst cylinder and shit went through the intake manifold and destroyed other cylinders. I've seen that many many times.

The better question is why a dropped valve?

If you drove that engine hard with a Type S tune, it may be a contributing factor. I cant tell you for sure because I dont run cars on "base calibrations" or "borrowed tunes" so I dont know how off it might have been.

No sense in crying over spilled milk... it's time to pick up the pieces and get her fixed. When it goes back together do yourself a favor, have it built by a professional and either get the right ECU or GET KPRO and have the engine tuned. DO NOT RUN A BASE MAP.

That would be correct. Tensioners that are worn out tend to give up the ghost when oil pressure is low (this is when the worn out parts are most needed).
