Costs about $400, but they test compression and a whole heap of other sh*t.Might check them out. Link to comment Share on other sites More sharing options...
TXR05 Member 181 Member For: 13y 8m Gender: Male Location: Brisbane QLD Posted 27/06/12 04:25 AM Author Share Posted 27/06/12 04:25 AM 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 ) Link to comment Share on other sites More sharing options...

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.

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. Edited 04/07/12 01:07 AM by TXR05 Link to comment Share on other sites More sharing options...

TXR05 Member 181 Member For: 13y 8m Gender: Male Location: Brisbane QLD Posted 04/07/12 10:54 PM Author Share Posted 04/07/12 10:54 PM 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. Link to comment Share on other sites More sharing options...
