Boost leak somewhere most likely.

The first pic is nothing, I have the same uncapped pipe there.

The second pic, I don't know what you are trying to show, but it looks like you need to have that vacuum hose going to the boost sensor (stock ECU??) teed off to the wastegate/boost gauge.

The third pic looks like the same style plug as an injector, but I don't know why it is down there. I can see behind it though that the ground tab is not connected. That isn't good at all.

As long as your is S5 with no emissions, it should be similar.

In the third pic, I think that might be the plug that connects to the oil level sensor on the oil pan, or maybe it connects to the transmission wiring?

OK, same order as your original pics-

#1- Rats nest lines to nowhere.



#2- Diagram of how I have my boost goodies set up.



#3- That is for the oil level sensor. Could not get a good pic since mine is covered in crud, and the flash didn't help, but here it is.

If you are going emission delete........you basically block EVERYTHING except for a select few.

-Leave the large port on the backside of the TB for the Oil Injector Vacuum spider (unless you are pre-mixing, then cap it)
-Leave the large port for the brake booster
-Leave the port on the turbo side of the UIM (pictured above) for boost reference
-Leave the port for the Fuel Pressure regulator.

Everything else is capped off.

That is really all you should have if you are emission free.
