Boost Guage Fitting

[t304vkcalais]

Just fitted a aftermarket boost guage to the 32 gtr(plumbed in between the pipe off the top of the blitz bov),

found it was running 12 psi, problem is now the bov's arnt making any sound and the boost is choofing back through the air box.

Why is it doing this , is it where we plumbed into? If yes where should the boost guage be plumbed into?

boost gauges should be piped into the plenum chamber. there is a pipe at the front and rear of the chamber. check it out coz thats where the pressure reading comes from the stock gauge.

Best place is at the back of the balance chamber is a black rubber hose that goes to a map sensor on the drivers side of the firewall, that is your factory boost gauge ( not to be a smart arse but on a GTR because of the 6 throttle bodies the plenium does not get vacume so the gauge wont read it ).

hey the wires on my apexi EL boost gauge seem to correspond with the cable leading from the map sensor....can i just plug it into that? or is it recommended to use a tee piece to a 'apexi' boost pressure sensor (which i don't have as i bought the gauge seconf hand)??

if i can just plug my gauge into the map sensor, will that give me accurate readings? or does anyone know where i can get an aftermarket boost pressure sensor?
