GFB diverter valve upgrade
Car had no issues what so ever apart from broken diverter valve diaphragm which is common thing for all electronically controlled blow off valves. Broken one: Stock option would do, but have idea to raise boost some day, with that in mind stumbled upon GFB diverter valve upgrade. Which is kind of pricy, but car in general isn't thing where you save money, so went with it. Instalation was straight forward and result made car act as promised, response after throttle on-off-on was better, also claim that this valve can hold any boost seems truth by looking into it. Now ready to raise boost somewhat.
