Back On The Dyno

Keep persuing Ian, or catch up with the Nizpro boys when they are in QLD (there is a post about this in the Nizpro sponsors section).

I tend to agree with both Adam and others. The Torque on these stock is supposed to be dead flat from about 2500 - 4500 rpm - I just looked at mine as stock and it was nearly dead flat from about 2700 - 5300 rpm. Yours falls immediately from peak torque. Now this might be nothing, but it might also be another indication that you do have a problem - and as mentioned before - the first place to start is the cat for this. (which means the mob you have been speaking to are not necessarily speaking out of turn - it is just that you don't need a complete exhaust, and you will only be having this problem if your current system is compromised in some way).

If the restriction is really bad it will create more back pressure on the turbo - which require more pressure between the turbo and the engine to generate boost. This may require more timing to be taken out - so that may explain in part the lower power figure.

The same could be true with the waste gate actuator so the suggestion made above is not a bad one. Regardless - have someone who has worked on these cars a fair bit do the diagnosis.

Cheers,

Ben.

you could try ringing capa and talk to them .

mabee send the box to them to get the latest generic tunes they may do it for you free if you jump up and down and swear and spit enough.

you may have 3 tunes the same as stock as a malfunction.

did u say it was from a capa dealer or a second hand box.

a capa dealer should be able to sort you out or they shouldnt be a capa dealer

my capa box is the best thing I ever got

I only used the generic tunes for 10 minutes before getting a CUSTOM TUNE its not worth the risk. 30-50000 dollars for the car -400 for a custom tune u do the math.
