For the past few months I have only been able to get about .6 bar of boost.
I run a standard GTS boost solenoid and thought this was faulty.
I swapped it with Busters old one, but this has made no difference.

Can anyone give me a suggestion as to what might be the problem????

I have checked all hoses going to and from the solenoid.

Without sounding like a dumb ass it may be down to your dump valve, a few people have had probs with dump valves on their GTST`s.

I have been running the same setup for around 7 months with little problems.
The car did cut out at junctions but I seem to have sorted this out.
When the I lost the boost I had not changed anything so this I why I was a little confused when the replacement Boost Solenoid didn’t work

have a looook under the airbox, and check the intercooler pipes. Had a similar prob wit mine, took a month to figure out it was that.

Just an idea.

.6 aint shy though is it ? Standard set up I think you would be pushed to get much more than that anyway.

When you put your foot down you stay at .5 boost till you hit about 5000rpm you get a extra .2 boost.

Rod Bell wound my HKS BOV screw right in.

Perhaps your wastegate is opening, could be getting weak. Can you borrow an actuator off someone?

When my intercooler pipe was leaking air it started to miss and pop when the boost pressure got just past zero. This was a big leak (hose clip not done up) so if yours is an air leak it will be quite small. Re-reading that i'm not sure how relevant it is :D

I'll get the car up on the ramp tomorrow and check everything again.
Is it easy to change the actuator???
