Hi. I have recently decided to play around with the dump valve on my astra GSi to see if i can change the sound to a more wastegate sound. I have disconnected the standard recirc valve and then blocked the bailey dv off as well. It sounds great and i find the car boosts slighty better, as have been having problems with a flat spot with the boost after cs3 map. Is this a bad setup and likely to cause me problems having both the bailey and oe dv blocked off?
