Brought a turbo to boost lab with less than 3,000 miles to upgrade for a bigger compressor wheel and turbine wheel. It was balanced and put together by boost lab. Wright after installing the turbo it came apart. When I brought it back to boost lab without taking it apart, as there policy says. They told me there is nothing they can do. Folks if you have a turbo that needs service of any kind it's usually better to send it back to manufacturer or a shop that is known to back up there work. This shop cannot and will not back up there work.
