I have 2 holes on my turbonetics evo wastegate, 1 on the cap and 1 right below the cap. is the one on the cap for air from the outside and the bottom one hook up to the turbo?

 

wow, no one here knows this? Why the hell would turbonetics do it like this then?

 

Tial wastegates also have 2 hookups. On Tial's, the side one is used and the top is not unless you are running an EBC.

If you understand how a wastegate works, you should be able to look at it and tell which one to use. Boost is pressure, pressure is used to compress the spring. Compressed spring = boost being governed.
