AS I SIT AT MY DESK I WAS REMEBERING THE LAST TIME I RACED,WHEN I STARTED THE CAR PSI WAS AT 6 I DIDNT ADJUST BECAUSE THE DAY BEFORE I SET IT AT 7.5.WHEN I MADE A PASS IT WAS ACTING FUNNY LIKE IT WAS STARVING FOR FUEL.I ADJUSTED IT TO 8 PSI AND IT RAN FINE,IM THINKING THE PSI REGULATOR COULD BE BAD OR MAYBE SOMETHING STUCK IN IT.
