Wife and i went out tonight, and the drive home was a little spirited. Took some back roads and got on it a little. While i was winding down to cool off the engine a bit, i noticed that the turbo sounded louder than normal. Whenever i built boost, it made a loud whoosh, but there was no power behind it. I'm assuming its a boost leak.. But i don't see anything loose. Its a base 12 wrx, stock.
im sure i shouldn't drive it in for service..
Any input would be appreciated.. I would like to know what's up before i bring it in.
Sorry if i left out any details.. It just happened and I'm pretty bummed out.
