Hi guys, I know this is quite a common question for AGU owners so I decided to install a bleed valve on my 1999 A3 with an AGU engine. Little bit of background, I currently have an aftermarket turbo intake pipe, pod filter and front mount intercooler. I have a digital (very accurate) boost gauge wired into the vacuum line going from the inlet manifold to the dump valve (right next to the fuel pressure regulator). I was seeing around 9 psi standard and with the bleed valve I am hitting and maintaining 13psi throughout the rev range. It certainly pulls a lot harder and for the money I spent I am very happy. I might push it a little higher in the future but I am very happy for the moment. This post is just to prove that you can do it (note AGU's don't have a map sensor which would possibly throw a fault code with a bleed valve installed in other cars). Just wondering, is there anything I can do to the actuator itself to increase boost. I have heard that you can tighten it so it doesn't open as much and will spin the turbo faster but I'm not sure how true that is.
