What tires are you guys running? I ran 11.5 on shitty nitto's before the converter was installed. My 60ft was in the 1.8 range leaving off idle and rolling in gradually. Had I had good tires on that set up I think I could have been lower 11's easy. I have not even launched hard yet with the converter and been 10.80's.
It's not tires my car dead hooks on these crappy 60' times.
