When fitting a boost guage which pipe do you connect it to in the engine bay? I Have heard there are certain pipes to fit the pipe coming off the boost guage. If the guage is not fitted to the correct one it obviously reads wrong. Does anyone know which one? Any pictures as well

 

of the throttle body its the middle vaccum hose.

 

Same as above

3 hoses on top of engine, 1 should be quite thick, going to your DV and othe 2 sholud be heading off left (ish) use middle 1

Just watch out where you run your hose for the guage as parts in that area can get VERY hot and melt the pipe

 

Just had a quick look. The boost guage pipe is connected to a T piece with a brass re-strictor in it. This pipe then goes down to a control unit which is red/orange underneath the waste gate solenoid. Sound about right?

 

Have a look here.
