    There is no mechanical problem so difficult that it can not be overcome by brute strength and ignorance.

    changing the FMC table is pretty much always a bad idea.

    if you're trying to force more line pressure, there are better places in the calibration to do so.

    No, I pretty much get the picture that the pressures go through the roof. I am a master of the obvious.

    Car was trailered in for a tune, fresh motor with AFR heads and fully forged rotating assembly, motor stalls when put in gear like the TCC is always engaged.

    Why do you want to modify the main pressure table?
    You may have other issues
    I always modify that table but in small percentages and only the last 2 columns, I rarely need to do other changes

    To set it back to stock.

    I have never seen a pressure table with zeros like that, you may want to copy the whole table from a known stock tune and tweak it for your needs
