Anybody got a good link on how to install a manual boost controller on an A4 2.0T FSI?

This doesn?t work! Tried it and the car is too smart! Had to chip it instead. Did BSR (www.bsrab.se choose english) and got a healthy 262 bhp and 380 NM torque.
Next step is turbo upgrade. Any ideas?<ul><li><a href="http://www.bsrab.se">http://www.bsrab.se</a</li></ul>
