Hi Turbotonic,

I have the exact same problem. Is your boost still working? My r34 gtt stock guage sometimes just stops reading. The needle will just drop and stay there for a while. Boost still works fine and cars performance isnt affected so i'm not fussed. I've been told it's the Boost Sender Unit.

If you manage to get a confirmed source of problem for this let me know!

you mean the stock one? if so it is electronic, so if you can get aftermarket mechanical ones, they are far more superior.

yes snoopy it looks like we have the same problem nothing is affected just the guage wont read im gonna change the hose coming from the air maniflod to to the guage

ill let u know if there's improvments.

I think they maybe pneumatic to a map sensor, then electronic from the map to the gauge. So if anything check the map sensor/connections is ok.

I have this problem too, there are 2 other threads on this already, one of which i made, most of which the recommendation has been to replace the boost sender unit, do a search and you should find the threads, one even has pics of the unit
