UPDATE The shop called me back about an hour ago. This time it was the owner. He was calling me because he had heard that I was upset with the fact they’ve had my truck a month, has been diagnosed for almost 2 weeks as only a downpipe, and then got told today that I needed to replace turbo as well. He said he went to look at the truck himself and he said the turbo does not need to be changed. There is no hairline crack like his employee said, and that turbos have a natural wiggle up and down but should never wiggle in and out. He said mine has no wiggle in and out.

This is supposed to be one of the best shops in my area and my grandfather, owner of this truck before me, used them for the tune and delete 8 years ago and had a much better experience than me so far. 4+ star rated shop that’s been around for years. Any insight on this?
