Have you compared it to your lg readings to eliminate a faulty gauge?

 

[LEE69]

You can hear the car mate.

 

[Trublu07]

Mine has started surging under full boost since I had my map done.

I spoke to Will at P-torque and he has told me I need get a n75J valve. He told me it's a common thing and to upgrade them.

Mine does it in 4th and 5th surging between 20psi and 15psi.

yeah 15-20 here to N75J, tried one before ages ago, but can't recall if it was before the map or not.hmmmmm.

Also facebook mate said "hole in a boost pipe or hole in the intercooler" smoke test in order first i think.

Mine does this some one said n75 valve is at fault I also have a further fault, when I Change gear quickly it only boosts to 1bar?? I'm stage 1 LC

 

[leon_lee]

mines doing this but only intermittently and only on part throttle, you can hear it get to normal maximum boost then just keeps going, eventually it dumps all boost and then does it all again. I've been told it's the N75. Going to order one from Ebay soon.

 

[cupra-barn]

I havn't changed mine yet as it's only happened this week.

Keep us updated bud

 

[LEE69]

I have 2 N75 one is new and it does it with both don't know anyone with a J close though to try.

 

[Pyro]

[LEE69]

No, nothing at all.

 

[Pyro]

odd???? you rechecked the 007 to make sure it in puker and did you change the rubber on the service? might of just missed something???

 

[LEE69]

Yeah changed it all to the new bits.

 

[cupra-barn]

Is the 75J metal as opposed to the the standard 75 being plastic?

 

[LEE69]

I really can't recall the difference, i know they get plumbed in opposite.

 

[Trublu07]

With the smoke test if you do one pay attention to the s hose at side of inlet. Smoke didn't come out of this when I did my test but it had a leak at one of the inside corners.
