there is a diagnostic dyno near my place. Costs about $400, but they test compression and a whole heap of other sh*t.

Might check them out.

So I still haven't figured out what the go is! anyone else got anymore ideas ?

It feels as if the cams are not kicking in like they should be! drives fine up untill 3500RPM where the power difference doesnt seem to change much from 3/4 throttle to full throttle.

makes all the noise like it wants to go, but just goes no where. Not logging any error codes, making 13.5 PSI instead of 12 PSI. Took it to the dyno who told me its because the engine is old ( 90,000KM )

Could a fault O2 sensor cause this ? TPS ? Or could this be because of my non genuine coils ( doesn't misfire at any RPM or boost ).

Just lacking the suddon oomph of boost at 3500 ( but still hits it fine )

Probably wrong maybe check the vct plugs under the coil cover for looseness

I had a similar problem lot of boost an no power, pain in the arse to find the problem, but I found it an it was my turbo, it was rooted, my rear turbine wheel was damaged an that's what caused my loss of power. What I sugest you to do is put it on the dyno an see what power you get check the tune while your at it. I relise you have a manual mabey your clutch is slipping a bit.

turbo sounds fine though. Not clutch slip as it holds in 6th under load and spins the wheels easy enough.

What would be the best way to see if the turbo is buggered ?

It still holds boost and makes it just fine. On the shut down it all sounds normal.

I don't know if it would be the muffler, would that make the car sound different?

The odd thing is the car seems to have more power in the morning. Right after the car warms up it's got a fair amount more power than what it does if it's been running for a couple of hours.

Yet the intake temps remain the same. Well maybe 5 degrees different.

I'm going to take it back to the dyno when my tax comes through. Hopfully it's something stupid.

I was watching a vid when I first got the car, and it deffiently went alot harder than what it does now.
