Yes missing 3rd is common with a stock shifter, well out of about 200 runs, i've done it 3 times...too many, anyways i raced an 01 cobra vert, he ran 14.3 @98mph, it was very, very humid, i beat him barely, and he had the complete kenny brown suspension and subs, i really expected more form a 4v cobra, put me in that cobra, and watch me powershift a 13.8 1/4

, i dont know why a cobra would run 15...anything, but elevation maybe, and missing shift(s) maybe, are you sure your looking at the right timeslip? maybe the guy left the traction controller on? But i doubt anyone would drop 45k, or whatever to run those #'s sorry.
