My wastegates are rattling pretty bad at this point, so I think I might pull them for a rebuild and stuff in some bigger wheels while I'm at it. I thought about using turbo lab, but recently heard some bad things, plus I would have to mail my turbos out. There are a few companies in Houston that rebuild and vsr balance but I need to know what spec wheels to buy. I'd like to make 500-550 whp and be able to pull to redline. What do you guys think I should do?
