Hi guys I know this possible been asked before
But were would you t into for boost gauge

I have t into top pipe comming from boost controller and seems to be working apart from when I accelerate the needle starts jumping around
Thanks

 

What make of gauge? some cheap ones do that.

Mine feeds off an unused nipple on the inlet manifold, it was blanked off before.

 

Mine fitted as above.

 

Pictures? My mates trying to fit a boost gauge at mo.

 

Mine connected via t red pipe going into top of boost controller
Boost gauge unbranded but flickering when accelerating

 

Just look behind the alternator on the inlet manifold and there is a rubber cover on an outlet on the manifold take that off and connect the boost gauge pipe to it.(classic impreza).

 

Was connected to middle blue pipe
But that gave me -30 vac and didn't got into boost until flat out then only hit 11 psi
