Hi guys,

Got a issue with the boost on my standard cossie this is confirmed as it was on the rolling road and it is only putting out 186 bhp. I have been told I should have 0.8 bar of boost. I only have 0.7 and it drops off after 4500-5000 slowly to 0.55 bar. The actuator and amal valve have been changed for new ones and it is still doing it. The whole inlet has been smoked tested and there are no leaks. The compression is 155psi across all 4. I have tested the turbo and that can hold the boost so I'm now guessing it is electrical/ecu related does anyone have any ideas what it could be. Its starting to really annoy me now.

Regards

Matt
