Couple of questions about S4 FC [pic]

Hey!

Could someone tell me what this is, and if it needs to be/where it should be connected? Can't find it in the haynes manual, and I'm currently installing Haltech.



And another question. If the vakuum isn't connected to the S4 Twin scroll turbo, will it be in the high rpm or low rpm position?

In other words, no need for it? I have removed the other EGR stuff and replaced with block off (visible in picture).

you should circle which part you're referring to. You realize that hardline coming from the turbo is the oil line right? I can't tell from your picture if it's even connected to anything.

that nipple is suppose to go to a hardline but it doesnt look like you got the hardline so a block off plate should be good.

It does actually. Have to change clutch every 2000 miles

Anyone have a tip how to use the twin scroll system with Haltech?

I was referring to the actuator that's not connected. I'll keep that in mind next time I have a question!

All the hardlines are removed.


And another thing: Anyone have a guide to a double trottle mod?
