Why?

I have been trouble shooting the boost problem in my car. Well I figured it out a little bit ago but just got into fixing it. I took off the intercooler piping to find that my wastegate control and turbo precontrol nipples were looped to each other. Anyone know why this would be done? Here is a picture of what I mean, the 2 top for the solenoids are left untouched but the bottom that go directly to the wastegate is looped with the precontrol.

I have already taken it out and waiting for the engine to cool to correctly put the hose on it, I am just baffled as to why it was done.

 

Do you have an aftermarket boost controller on the car?

Or someone tried to go non-sequential?

no boost controller and has been sequential since I bought it. I am going to put a boost controller in probably this weekend. It just baffled me why it would be like that, I looked at simple sequential and non-sequential diagrams and don't see it on either.

 

I don't think it's looped to be looped, I think that's just a way to cap both of those nipples. Instead of using 2 vacuum caps, you just use 1 short piece of vacuum line.

Get a copy of the vacuum diagram and go to work.

job is already done 5 hoses were disconnected, finally figured out how to read the diagram. Made it so much easier, everything is working correctly now, besides the boost spike but not worried about it and will fix it soon.
