6.5 diesel wastegate question

Hi guys. I have a question, I`d be glad if someone could answer it. I want to know if the wastegate on the 6.5 turbo is normally closed or open during idle. It's a `94 2500 truck, automatic. In my truck the wastegate linkage its all the way towards the firewall, but I don't know if thats the open or closed position.

Any codes?

If no code for wastegate you have no problems.

If a code Get a repair flow chart and check it out.

Check vacuum at idle atend wastegate vacuum line.
It should be 15 at idle.
