I hope you guy's don't mind to have a Dutch guy on your forum 
But you german guys do know a lot more of the volkswagen car than in Holland.
Can someone tell me what kind of Turbo is installed in the Golf V GTI? Or can anyone tell me what the maximum pressure can be for this kind of Turbo?? A type and number or something like that. I want to tune my turbo by adjusting teh pressure of the turbo by putting a valve on the vacuum of the Turbo.
Hope to hear from you guys.
Greetings Pascal
