small leak in your boost line...

waste gate might not be closeing totaly.

i dont really know but they sould like possibilitys

Edit: might be low on compression

ah goodie. so i'd be better off getting it checked out and having a compression test done?

Check for any obvious leaks firstly, that will be the easiest thing (Intercooler piping, gaskets as well).

Make sure all the VAC lines are plugged in where they should be

Compression test you can do your self also, with a compression tester ($50). There is a write up somewhere on the forum on how to do it, and most of the testers have instructions on the back.

Good luck!

Similar story with me (you'll be able to see my post 'Leaking boost charge')

I can't find any leaks but the boost isn't coming on like it used to. I'm not sure what it is, whether it's the turbo (wastegate), intercooler (highly doubt it), exhaust (doubt it too).

What would a mechanic check for if he was at this stage?

After a compression test, would he take apart the exhaust to look for evidence?

Would he take apart the wastegate?
