Not upset or worried at all, these things happen and at the end of the day its only metal and that can be fixed, just a shame I can't bring it up on Sunday. I have had a few hundred miles in it and they were brilliant!!
There is nothing in that engine bay that hasn't been cut, welded, fabricated, changed or modded, nothing is standard or straight swap so something as simple as a turbo not working properly is the least of things to worry about, especially as it is under warranty.
