Does anyone know how to adjust the PFC to lower boost? I have a full exhaust and sometimes I can hit 14 psi. I want to get it back to 10, someone said something about duty cycles or something... any info would be appriciated

via commander

go to settings then boost..

youll have 2 settings to play with for setting pressure

pr is for your primary boost value

sc is for your secondary boost value

you set your pressure here

70kg/cm2 = 10psi as reference..

adjusting your base duty percentages allow you to achieve your target..

the first number is your target boost. the second number is your duty cycle % that changes how fast it opens and closes the wastegate. you have to play with it a little bit....
