All of your passes proves my "PCM Learning Conspiracy theory" The first and sometimes seccond pass on the car will allway be crappy. The PCM has adjusted to normal driving, after a few passes, the PCM will be working better and the engine will increase performance (to a point).

Now I need to check the "Reseting your PC will increse HP" theory.

I want to test the car first right out of the street, then a second run just like it is, for the third run, Reset the PCM and do a fourth run for consistency.

My theory, by just doing this, the car will show a big HP and torque gain in the last two runs. Proving the "Learning PCM" theory.

Hmm

In order to do that and to control the conditions as much as possible, the temp/time of day has to be relativity the same. The time between runs has to be the similar. The weight of the car and the driver (ß-- no pizza etc) has to be the close. When I did my consecutive runs the car dropped down (let’s say a max of -.3) and then leveled off in performance. BTW, that was one of the reasons I put the times of the runs in my spreadsheets. I also need to add a temp and mod column to spread sheet. Finally some mods will only help the 1/8 mile times while others will only help the 1/4 mile times. But you are on to something.
