I have stock conti's and haven't ran them at the track since I added more than my nw intake. I used to lower my conti's to 26 psi and still hookup was decent but not great. I never ran them on nothing more than a trophy night. So track prep was not fantastic. I have a vid when I went to the track with my pulley and no tune yet. Needless to say it was scary. I'll see if I upload it later.
