For those who have a boost gauge on the n54, where did you tap your boost source from? I currently have mine on the old nipple on the intake manifold that's behind the throttle body and it only reads vacuum, no boost.

Maybe Nexons gave up? Try meth bung or spacer/adapter on map.

I'm using the stock nipple on the intake that the diverter valves use. Works fine.

The intake manifold is the preferred and most accurate area. That area would read boost so if you are not getting boost but you see vacuum then perhaps the gauge is faulty.

I'm glad to hear that although easy driving isn't really how you set standards. I witness turbos go out on two n54 just last Saturday at the track, one n54 with less than 10k on turbos. You got boost reading yet? Try another location to determine of gauge is faulty.

I did 8 pulls last Saturday vs some amgs and Gtr and she is still fine.. Maybe my tuner did a good job who knows... And I did try to tap into the boost line that goes to the rear exhaust flapper and still nothing

Maybe the installer has magic fingers....who knows?

8 pulls huh? That's nothing. On track, on average, lets say 20 minutes session, 2 min track, with 3 straight (so 3 pulls), 8 laps because you have 1 warm up lap and 1 cool down lap, which equals to 24 pulls. That is 1 session. You do 5 to 7. So 100+ pulls. Even is if 1 straight that is over 50 pulls. So yeah, when a car can do that I can say is solid.

Anyhow, boost gauge.The flapper is vacuum operated with electronic control, boost does not go there, it opens and closes even at idle.
