I've had my PFC installed for about a month now and its been able to control my boost very well. When set to the low setting (.79 Bar) I was getting .79-.80. This last week though I'm only getting .73-.75 Bar. I turned the PFC to the high setting (.89 Bar) and I'm only getting ~.86 Bar. Otherwise everything is fine, the boost builds quickly and the transition is fine. The only thing that has changed is the weather, its been much warmer this week than when I first installed the PFC. If it's not a boost leak then what else could it be?

 

The warmer air does that. Use higher for higher temps, to get a certain level, and in the cold use lower settings.. You just have to find where your car reacts best with what weather conditions... BUT that is perfectly normal...

 

Thanks for the reply. I thought the PFC would be smart enough to compensate for the warmer temps. Anyone know about what temps its calibrated for then?
