You need to start keeping records of the track conditions, tire psi, IAT, ECT and all that. Best of all, get something to datalog the runs, HP Tuners is invaluable at this point.
If you ran 9 runs, that means you probably were not getting enough cool-down time. No doubt if you run on a cooler day, where the high is 65 degrees or so, it will run a 14.9xxx. with a good cool-down. iirc, ORP did not have a source of water for cooling, so that makes it tougher.
