Boost by gear setting

There is an option to use a pressure vs duty cycle setting and gear based duty cycle(which ignores the pressure vs duty cycle). Any reason one would use pressure vs duty cycle over gear based? If I want 15 psi what do I care what the solenoid duty cycle is at to acheive that? I know it's nowhere near maxed out.

You must still setup the pressure vs duty cycle table or the ECU will not know what duty cycle will produce a certain pressure.

So it does not ignore that setting? Why even have it then? Seems redundant.

Gear based duty cycle

This setting will output a duty cycle based on the boost by rpm & gear table. The pressure vs duty cycle table is not used with this setting.
