Not sure if the standard diverter valve was leaking boost, but was advised to upgrade diverter valve as i was considering a remap as the car seemed to be a bit lacking in performance. However this upgrade to the diverter valve what a different changed my standard car (VRS Fabia Twin Charged Engine) to a more responsive quicker car. Can not recommend enough for people to buy GFB diverter valve upgrades for their vehicles worth every penny, having a remap now is on hold but i know for sure if i do get a remap performance will be even more amazing and guaranteed no boost leakage.
