Having a spot of trouble, sometimes when the car is boosting up at approx 4500rpm the boost cuts 4 a split second, its enough to thro you forward in your seat.
Have heard in the past that something needs taking off and cleaning, a valve not sure which one could any one post a pic to show me please
Thanks.

Cheers for the pic myblackwrx
Right have cleaned it took it out 4 a drive felt much better, boosted smoother and a bit harder i think. It was fine for about 15mins then got on a fast strech of road put my foot down from about 3rd gear and it cut about three times its only a split second that it cuts for,never does it unless the boost is getting stronger kind of mid boost any iders greatfull cheers

can you go above 4500rpm?

Could be a Maf sensor problem,did it on mine,did take it off and clean,but didn't help...

But got a new one supplied by HDC SUBARU - parts .. breaking .. salvage .. consumables.. mail order ask for Howard..

All workin fine now....

I have similar problems but it feels like it misses( spark plugs?) at the higher rpm.

always worth checking plugs and leads/coil packs.

I went to clean my boost solenoid the other day but wasnt sure what it looks like on a MY00 classic?

Theres nothing anything like what is shown in the pic above

Anyone got a pic of the boost solenoid on a my00 classic?

Cheers

fuel cut ? check your maf and do you have a boost gauge ?

follow the pipes back from the turbo, it's on the inner wing and has 2 pipes on it.

Also no boost gauge

Followed them back and they lead to a small cylindrical unit which is light blue in colour. Also has 'Denso' on the bracket holding it in place...is this the boost solenoid?

cheers

One thing 2 add. Been reading up on here have been running under 1/4 of a tank of fuel some times latley because living on the isle of wight sul only get delivered once a week and the garage is always out when i get there could this have anything 2 do with it? Not sure if it always happens when the fuel is low tho

sounds like it does it look a little like the one in the pic as mine was not quite the same not blue, but rubber mounts

The one on my car looks nothing like the one in the pic above

I have a 99Uk Spec - had this problem only a couple of months ago - Went through the process of cleaning - I was told to use a brake cleaner - it worked for a few short trips, but the problem returned when I was opening her up on a long stretch.
Eventually I replaced the Maf Sensor and the problem rectified. Cost £130 from Subaru - took 5 minutes to fit (myself). And now she's purring again
I think you can get cheaper - I think Bosch do an equivalent for less cash - but i decided to go with Subaru, thinking maybe you get what you pay for and I think the one that was existing on my car at the time was an equivalent.
Good luck though

Havent cleaned the maf as yet will give that a clean hope that solves it if not maybea new one. When i cleaned the boost solenoid a lot of oil crap did come out

All cleaned now but still a bit wary to boot it yet and properly test it, its really not nice when it cuts makes you look really stupid also not to good for the car i would think
