Welcome to the forum.

Before someone tells you to search "Supercharger pump" or something similar, you will probably discover it is the intercooler pump that is going/gone out. I had to take my car to a dealer in Kansas City twice before I told them to check the IC pump. They asked why I thought that, and I told them to just do it. A day later they called all pleased with themselves and said they discovered the problem was the pump to the turbo! After I told them that I hoped my car did not have a turbo, they admitted that they have never seen an SRT6 before, let alone work on one.

You will just have to take it back and demand they check the pump.
