Careful trying to adjust line pressure, it likely doesn't work like you think it does. The PCM has no clue what the line pressure really is.

The maximum line pressure scalar is not line pressure, it's the highest column (or interpolation between columns) of the force motor table that can be used. Putting a higher number just sends the PCM off the end of the table where there is no data, my guess is that it sticks to the 96 "psi" column but I don't know and have never really looked into it. Just never go above 96 with this scalar.

The main line pressure tables are not in pressure, they simply refer to the "pressure" colums from the force motor table.

The force motor table could be used to adjust the maximum possible pressure by lowering the current in the 90 to 96 "psi" columns, but you have to be careful when doing so and should only do so with a pressure gauge installed.
