Took it off yesterday and found I had quite a bit of shaft play. Would that be the reason why I have a bit of turbo lag? And as for that tinkingish sound, my wastegate is very bad. I have another TD04 laying around that I just kinda compared the two & there was a huge difference in quality. The newer one didn't have rust & **** on it. I'm having some local guys help me install the new one on the 9th. Hopefully it goes well!
