Hi all,

Just wondering what the standard booast pressure should be, as on my gauge I'm spiking at 0.75-0.8 then it drops to 0.7 then it slowly drops to just below 0.6 by 6k. Does this sound right as I seem to be down on power on the rolling road?

think its about 8psi standard

 

I always thought it was 0.7 which is just over 10 psi but I may be wrong. Just trying to find out why I'm down on power.

 

What power has it made and for a standard setup on your rolling road?

 

0,8 - 0,9 bar on a 4x4

0,7 bar on a 2wd

 

It made 189 at the engine on a dyno dynamics rolling road. It has had a new actuator and boost solinoid but still no change. The turbo doesn't smoke and there is no play and freely moves. I think my next move is to change the charge temp sensor as that is meant to drop the boost by 0.2 bar if it is sensing over temp.

Oh and compression is just over 150 psi on all 4 cylinders.

I'm open to any ideas?

 

Can you trust the RR ?, emissions from the RR should give a good idea.

Yes I can trust it and the emissons are good. Is the boost meant to tail off on these ecu?
