i just had my 33 tuned last week, no knock above 30 until tonight..... i decided to put my foot down in 2nd (didnt reach the limiter) the knock was going ape sh!t and hit 98 so i did the same again to see if it was a 1 off, but it went to 60. i was stressing out a bit so i left it sitting for a while. just came back from a drive putting my foot in 2nd through 3rd and it only went to 30..... im hoping it was just the warm weather causing it to rise.....
