OK I am not really happy right now.. Just got back from the track.. first night open and all excited cause I installed 4.10 and have been waiting all season to run. Previous best was a 14.1 and hoping to break the 14.0-13.9 barrier. First run not so hot... find the time.... 14.5????? ok ok calm down.. second run... ooo better better..... get the slip... WHAT!!! 14.5 again??? ok maybe something is up... run again get a 14.3,,, ok time to go home. What is going? Why am I running so crappy after the install.
