Not sure if this is a problem before 'cos i have never noticed but when accelerating more noticable in forth the boost varies from 0.8 to 1.0bar? But today even stranger as the boost reached 1.0bar and then waived around the mark??

Not sure if could be a leak in the pipework?

Wierd

any ideas?? http://bbs.scoobynet.co.uk/confused.gif

A couple of questions.
What year is your car?
Have you noticed any whooshing type noises indicating maybe a leak?
I had a 94WRX that started losing power and at the same time started making a whooshing noise (like the release of pressurised air, which I suppose it is).
To cut a long story short it turned out to be
the pipe that connects to the underside of the intercooler. The Point where it connects to the intercooler has 2 bolts on one side and 1 on the other. A bolt had actually dropped out on the side with only the 1 bolt, and under boost was flexing apart.
Best of luck.

My car is also a MY94 WRX

But I have not noticed any whoooshing sounds I don't think . I will have a good listen today and check those bolts.

Thanks
