Your vanos seals are important to the performance of the engine. I noticed that I was down on power at wide open throttle on the straights at Hockenheimring. I made a smoke tester and used it to check for any air leaks in the intake/engine and found some on the vanos seals and disa valves. This probably threw off the MAP sensor since more air was getting into the engine than it could measure. I show you how to fix the vanos seals in this video.
