Hey all,
I have a 2002 gu zd30.
I have installed (about 6 months ago), catch can, boost and egt gaudes, 3" exhurst, dawes valve and needle valve.
All was going ok till yesterday, it is getting to much boost, was getting about 16 psi before safe mode cut in, now getting about 20psi plus.
I cannot work it out, help me please.
or if anyone knows someone close that can fix this for me please let me know. (Im in Maroubra/sydney)
Cheers
Phil
Cant you back the Dawes valve off a tad to bring the boost down,
Have you done anything lately to produce the higher boost
04 ST 3lt auto, not enough Mods to keep me happy, but getting there
I have tried, backing off the dawes, doing it up, i have tried the same to the needle valve, nothing makes a difference.
It started doing while driving home yesterday
Its doing my head in.
So your hitting 20psi and no limp mode? Or getting limp mode?
no limp mode at 20psi.
Before i was getting limp mode at 16psi
Tells me then your boost gauge may be faulty. Can you get a hold of another gauge?Originally Posted by Rex13
20psi wont hurt the motor anyway. My GU was happily running at 25 psi day in day out, same the TD's GU.
ill try and get one tomorrow and try it
Just took it for a drive and it goes into limp mode now at 25psi.

Now that it could be the gauge, which ill take back for a replacement, ill need to re-adjust the dawes/needle valves, can someone tell me the best way to do that as i cant find my instructions that came with them.
Cheers
