“Nightfire Nationals at Firebird Raceway, first time using it and after coming from Woodburn the weekend before. I setup my delay box and go make a time run. I am .00x, then first round I am .034 and get lucky. Second round I’m .034 and get lucky again. I am making comments that I can’t hardly believe that my reaction time is off that much. Normally I would say well I timed the tree on the time hit and roll some out in this scenario going to round three. Then I was like oh s*** I have that logger, lets see what it says. .251, .251, .253, so now I have proven its not the car, its not the track, it’s me! The rest of the day I am deadly on the tree .00x because I have confidence and made myself get up on the wheel. Without this I am rolling some out and without a doubt would be Red third round.”  – Tim Wurtz
