I just installed some new JBA Cat4ward headers and went to the track last night to see if my 1/4 mile times would improve. I only got to make 1 pass, she went 13.33@102. My fastest time prior to the headers was 13.5@100. My 60' times were almost identical with pre and post headers, 2.10. (somebody needs traction)

Does anyone think a re-tune is needed because of the new headers?
