Forge 007p leak test

[tstrahonja]

My cupra doesnt boost over 0.8,0.9 bar. It used to spike to 1.4 and then slowly drop..
I tried boost leak test with a biciyle pump pressurising the system and DV starts to leak back into intake when i pump in 0.6, 0.7 bar.
Would that be my problem?
Or is that normal?

Could be , my spring was weak and leaked boost (green) so I upgraded to a yellow spring

Holds boost ok under 0.7, then starts to leak.

Have you tried reversing the dv? To see if you get the same symptoms?

Push the piston up inside the valve.

Cover the nipple with your finger.

Let go of the piston.

If theres suction on your finger which holds you have no leak. If there is no suction on your finger you have a leak and need to contact Forge for a service kit.

forge isnt mine, just borrowed it from a frend to try it out.
be4 spending money on another DV i just want to make sure that mine is broken.
i am still unsure if mine is broken, and should DV leak like on the picutre.
