Sure. Your wastegate actuator is activated as the mechanical diaphram inside receives boost. The closer the vacuum/boost line is the less distance air is traveling. While this seems like a novel idea because it is hard to grasp that distance REALLY does matter with air travel, the wastegate receives a strong "clean" signal the closer the line is to the turbo outlet. On high horsepower applications, the wastegate signal usually is tapped into the compressor outlet housing itself. A split-second of high-boost application can wreck your engine if the wastegate is not able to react in time.
Don't believe me? Call any speed shop or race shop and they'll tell you what I'm telling you. Running it to your throttle body is dangerous if you start to boost anything worth being happy about.
Some people do run it to the throttle body - but this is incorrect and dangerous. The signal is not going to give the wastegate the correct reading in time. You can risk this yourself, but having worked on high-horsepower engines for a living, we always ALWAYS make sure the signal is as close to the turbo's outlet as possible.
