id say a leak.. check for air leaks.

most prob air leakage as well... mine had a bad string of leaks.. only found that out on a dyno at ASG.

my leak was coming from my silicone intake as well as the cracked silicone hose on my fmic.

make sure the part of the silicone intake connecting to the bov return hose is properly connected. best is to have a metal stopper there and set bov to fully atmospheric (if u have a aftermarket one).

Lil' cracks on intake hoses = hell loads of dramas, my advice is to get it on a dyno to diagnose the problem so as to avoid running the car crappy and fiddling what's wrong and what's not

adding some more details:
car will hold stock boost(13.8psi) fine ist only until around 4500rpm it cuts and no power at all like clockwork
today i was driving at 80kmh dropped it back to third, gave it shit to see what would happen and actually lost speed :S

but yea no leaks in pipe from turbo to intercooler, or intercooler to manifold.

maybe the actuator on the waste gate??? anyone got a spare td04 i could borrow the actuator off? there's a six pack in it for ya

also whats the turbo solenoid and were is it located? pictures would be appreciated

cheers guys for all the help so far

cheers for the help but its not quiet like these cases...
in the first thread he says he only gets 5psi whereas im getting normal psi until 4500rpm
and in the second he gets a spike then it goes back to normal, but with no power, this one is similar but no spike???

any other suggestions?
