When my car was lid/catback, my best time was 13.4 on cool, crisp day. After installing my TCI 3000 and Nittos last spring, every time I ran the DA was 2900+, so at the end of the season the best I had done was a 12.98. I reached my goal of breaking into the 12's, but a .4 improvement from a stall and DR's was not too exciting. First day out this year, it was the same deal, 2900+ DA and another best of 12.98 - even with my new MT DR's. Well, Saturday a cool front blew through, the DA was 720, and the MT's were hooking. I was able to flash the converter - stomp and go. Result? I shaved .37 off my previous best, with .07 coming off my 60'.
