This car is 100% stock yet, so maybe next weekend i'll put in the up/downpipes and while I'm at it I'll inspect the wastegate area for cracks and make sure it is shut all the way. I'll report back. Sorry to thread jack but it doesnt seem right to make a new one for the same problem.
sometimes even when cleaned the solenoid is just worn out.

How are you tuning for stg2? Opensource or AP? If you are looking for a relatively cheap upgrade to a 3 port here is what I ordered:
3 port MAC valve 35A-AAA-DDBA-1BA 32$ shipped from amazon: is a good quality solenoid that they use in the AEM kits. Just need to get a few fittings from the local hardware store. They should be less than 5$. Obviously a tune is required. It will hold boost above stock pressure unlike the 2 port stock BCS. There is a review on it in the reviews forum.
