just dont use the fpr line, just because the gauge only reads positive pressure dosnt mean you need to fit it any differnet, well at the moment i cant see why not ? , anyway if you can get a T piece with a restrictor on the gauge side, as for making a whole in your intake , why ? the intake see's vaucume before boost also

Under the glove box, take the trim away, look up and you will see the ecu. Either take it down for easy access to find the pipe off the box and to add T junction. You will see it when taking the trim off under the glovebox. Five minute job. and if you feel technical piggy back the cables from glovebox to light up the gauge
I did the installation but it didn´t work.
I put the T on the line that pass by the passanger side.
Please, take a look on the pictures.
I did a test and this line is just producing negative pressure.
Maybe this is not the ECU line...
Someoone can give me any heads up?
The ecu line you want WILL produce negative pressure unless you are accelerating under load so you won't be able to see positive boost pressure on your gauge without driving on the road.. So you might have the correct hose already. (I can't tell from the photos)
That's the climate control recirculation flap actuator and is connected to a vacuum reservoir and one way valve Take the line off the ECU and it'll work perfectly.
