On the best runs I had the 2.8 pulley on it. With 14* timing commanded, but according to my log I saw 6* of knock on one of those. So yeah. Engine go boom soon.

The sad part is i normally see little to no knock. I've been running the 3.0 with 18* timing for like a month and the most i've been seeing is occasionally 1-2 degrees. But it's hit or miss and It's not even on the highest boost or even all the time at WOT. They really thought it was my gas today with a little trans slippage and heat mixed in. Either way i'm disappointed.
