I did 2 4th gear pulls back to back and the first one the knock was going crazy. But the second one seems to have relatively no knock at all?

I didn't look at the actual log until after the 2nd pull, that's when I stopped logging and parked the car.

I am including the 2 back to back logs for you to take a gander at.

 

Are your spark plugs still stock? Check out the gap and see if it's within specs. You can also check for boost leak.

Good luck
