My FD when bought had a vacuum leak, so the first thing I did was change to silicon vacuum lines, and I added a Power Fc as well. My mods are DP, Midpipe, Catback, no catalysts, Efini y-pipe. While changing the lines, I found that one line had the pill in it, but the other did not. Before the change to silicon, my boost was very uneven, and now after the change and Power FC, it feels even lower on power. Has anyone ever had one pill but not the other? Did it run correctly? Any help would be appreciated.

 

the stock control solenoids that the pfc controls are simple overwhelmed without a restriction in place like the pills. in my experience even at maxed out duty cycle, i could not raise the boost without a pill (or in my case HD bleed valves tuned to about the flow of the stock pills). the solenoids simply wont bleed enough air off of the actuators.
