Can we get a few more explanations of each number?

I am not sure if the pressure number should be increased or decreased to prevent the rocket from thrusting upwards half way through the launch.

Great mod by the way! Simple and awesome. Was getting tired of constantly managing launches after (probably) thousands of them.

If the question mark icon right of each parameter didn't help enough :): The pressure numbers are in Pa (Pascal) and relate to atmospheric pressure only! So it's not dynamic pressure. The higher the value, the lower down in atmosphere the vehicle will pitch over orbital prograde. 1500 is roughly 25km. I personally try to avoid that and set it to 0 all the time - because it's inefficient. Instead I fiddle with the pitch and speed parameter so the trajectory just get's perfect... So if your rocket thrusts up too steep, then pitch over earlier and maybe more. I build my rockets usually to have a TWR between 1.35 and 1.55, ideally 1.45. For that the turning speed is 85m/s and the angle is 12°.
