Not holding boost?

WX 2002 with 70k on the clock...

Boosts to 1 bar as normal and then drops off through the rev range to 0.

Does anyone have a clue??

Appreciate the help guys

Re: Not holding boost?

thats how it works,can't hold peak boost constantly....if you worried get it on a rolling road for a full diagnostic..

Re: Not holding boost?

Well it should hold boost untill you run out of revs in top gear.
Ive got problems with mine too!
Only boosting to .6 bar when it should more like .9 bar.
Holds .6 tho.
I have checked everything on mine and I am absolutely baffled
It was wierd coz I drove to work in the morning and it boosted fine.
Left it parked till the end of the day, drove home and it wouldn't boost passed .6
No smoke or a funny noises from the car. Very strange indeed !!
