Car looses 2.5 seconds?

[Poorboy_racer]

Crewing for a mates Supercharged BA at the Perth Motorplex yesterday. Cars been running high 11s no problem. Not changed anything but for some reason the car wouldn't run any better than a 13.5 yesterday. As min dial in is a 12.99 we were out 1st run. The air was really bad. But 3 seconds, no way. Now heres the rub. The meeting was abandoned as there was a power pole fire and there were no lights at the Plex. Is been rescheduled for the 2nd but nowhere is open. Just wondering if anyone had any ideas what we could do. Have not re flashed the car as the owner (not me) has no idea if the tuner has the latest tune in it or not. I suppose at this point we have nothing to loose by trying.
