Did you get out this weekend?
I really want to know if it was indeed your tensioner that was causing the problem. Mostly because I'm doubting myself, thought, and am wondering if your porblem is fuel related.

well i took the long way home (took the highway) and i couldnt reproduce the symptoms from befor. But got some odd KR readings... what WOT i never once got any KR but when i did just a quick slap of the gas 50% throttle after a short coasting i got 1* of KR and once i got a MASSIVE KR spike at about 18* which even with my foot OFF the gas 100% i took a few seconds (about 7- for it to come back down to 0*
WTF is up with that????

Possibly a bad knock sensor? They do fail from time to time.
That'* really strange. Espically for the KR to continue with your foot off the gas. 18*, that'* crazy. I would imagine that you'd have to really be able to tell that your motor was knocking by the way it sounds if it was pulling timing that much.
Did you notice anything different about the way the motor ran? Was it rougher than normal or anything?
I would probably start be replacing the knock sensor because they're pretty cheep. I'm not sure how hard they are to change, though.

I"m not sure what the KR decay rate is, but there'* a lag and how it slowly climbs down. It maybe a bad sensor.. but I"d check to see if anything is loose in the engine bay/exhaust manifold area that can be rattling against the block and the sensor is thinkin it'* knock instead ( you said slapped the throttle.. so I"m assuming you stabbed to 50% and the whole block & tranny shifted/twisted quickly so if anything is loose it MAY knock against the engine )

KR is typical at shifts when the engine dumps boost and when you first let off the throttle...
That does seem like a long time for it to linger though. Any other items that might be giving you false knock?
