DV12 Bailey BOV

just purchased a DV12 Bailey Dump valve, (VTA) looks like its going back on fleabay, many don't favour this type of valve, as it will probably suffer drivability problems relating to juddering on fast gear changes and shuddering when easing off the throttle from low boost.
VTA bov literally dumps air that's already been measured out of the system after the ecu has determined the amount of fuel to use so it runs the engine instantaneously rich.

thanks, lets see how things develop, won't be getting rid of stock valve, will have that on stand by if need be.
Bob Rawle did an absolute fine job when he mapped it back in January, it pulls like a train to red line, the guys a genius, knows the Scooby inside out.

the number of parameters he can modify is quite staggering to say the least.
Bob's own STi is having a major overhaul at Litchfield in Tewkesbury, that car is going to reach some serious power once all the big work has been completed.
