hello,

just got a boost gauge fitted to my p1, the car also has a hks vent-to-atmos dump valve fitted.

when driving along, the gauge shows the boost pressure rising till about 1.1 bar and then you can hear the valve dumping, the reading goes back to -200 odd. Also the same, if you ease of the gas pedal quickly..

just a stupid question really, does this seem right? or do i need to get it checked?

cheers

 

dump valve wont dump until u let off the throttle if it is dumping while on boost something is wrong
