Which boost reading is accurate? PFC or Defi
Today I have installed Perrin 3-port boost solenoid and now I'm able to control the boost above 1.1 bar. The problem is the boost readings. PFC shows 1.25 bar peak, but the defi's show (20 psi) 1.37 bar peak. Which one should i take into consideration while tuning the car?

Your PFC hand commander will read higher than 1.25 bar without a problem. Is the scale perhaps different ie kg/cm v bar ? That would account for part of the difference. Sampling rate may account for the remainder (missing the peaks)

Could it be if the PFC is pre97 that you're just maxxing the MAP sensor?
