so you were doing a WOT run, at 4678 RPMs you were at 21.5* spark @ 199 ect
@ 4748 is where your knock came in and pulled 4* of spark right?
do u have a cam?? im assuming its an auto cause of the gears....right?

i know when my car was tuned, they desensitized the knock sensors a bit to make sure it was actual knock, not something else. try that out. about 3-4 degress since thats what its pulling. If this isnt the way to go about it, then im sure someone will correct me

you may wanna try to play with the ve in that area. you could have too much spark for the stock ve. you modify one thing, it affects many if im not mistaken, shouldnt your ltft's be 0 when at WOT???
