Default Power Loss

Hey guys...

just asking a quick question about the power loss im experiencing...the car was running sweet as a few weeks ago after my service now its running horrible like i cant even feel any pull and seems to be losing alot of power and not moving anywhere almost feels like a non turbo...possible ideas i thought it would be was Turbo problems....or maybe even radiator or some pipes are loose somewhere.

what you guys think? any ideas? i will be taking the car back to tenagah motorsport where i did my 100k service very soon so they can check it out.
Its a 2005 sti btw.

cheers any help appreciated.

you will probably find you are much more familiar with the power output and that the car is running the same as before.

I have this problem I think it runs like a dog, but then take it away for a week and jump in and it is fun again. I think weekly mods are needed to satisfy .

Then again any little issue and I think it is bad, just over react sometimes myself I guess.

took the car in today and found out the reason it was losing power was because the turbo is only boosting at .5bar cause the stock boost controller solenoid is faulty so looks like i need to get a new boost controller a after market one most likely.....any ideas on what to get anybody?

Stock boost controller ---- just ring ASG, RMS or MMS and they will very likely have a factory one sitting in the shop left over from when owners cars were tuned using upgraded Mac 3 Port boost solenoids or similar.

Really no need to go aftermarket on a factory tune.
