You can't hot lap these cars in stock form, cause the computer pulls a LOT of power out once the car is warmed up. I went from a 13.7 to a 13.9, to a 14.2 and finally a 14.6 hot lapping it one run after another, with only about 3-4 minutes inbetween. Best thing to do it get some ice, chill the intake manifold and let it rest for atleast an hour to get the temp back down pretty cool, then make your run.
