I have a 2000 model s3, the only mods are a cone filter. The car had a new turbo a few months ago before i bought it. My snap on tool dealer let me borrow a solous pro scanner for the weekend. With the scanner you can take live data readings. So i pluged the scanner in and off down the road i went.
In 3rd gear the scanner showed the car was holding 1740 mbar boost pressure.
According to this site http://www.sensorsone.co.uk/pressure...onversion.html
I am running 25.237 psi !!!
I have had cossies, skylines etc and know what high boost feels like and my car dosent feel that quick.
