I was talking to a friend of mine who informed me that tuners look for peak cylinder pressure at around 12 to 15 degrees ATDC. Previously, I thought TF engines peaked at 18K PSI at ignition time, but it is definitely ATDC. RacePaks don't have a sensor for that, tuners use a different logging system:

which uses a pressure sensor spark plug. Pretty cool.
