If I use compressorControl.Start(), does that mean it will never put the pressure above 115?

Start() will always cut off at 115psi using the current KOP pneumatic system and won't run again until the pressure falls to 95psi.
There were some older KOP pressure switches that were set at 120psi and you might be able to buy a switch pre-set for 120psi.
If you can't launch anywhere in the range of 95-115psi, then you probably want to use your own code rather than Start().
If your goal is to launch only at a particular pressure each time, then you'll either have to watch the gauge and operate the compressor manually, or dump enough pressure each use to trip the pressure switch (by dropping to 95psi) and let it build up to 115psi, or buy a pressure transducer.
If it must be at 120psi every time, then you could force the compressor to run a minute more after the pressure switch cuts off to build up to 120psi.
