View Full Version : Reversed dump valve
Following RobDons advice from a previous thread i reserved the hyperboost dumpvalve on my Cupra tonight, but it made no difference to sound, it is still only slightly noticeable.
But spool up time was slightly quicker.
Anyone else done this and had similar/different results?
