Based on my experience, an indy shop does not exist in Miami for a Porsche car. I will be happy to explain, but I promise, I have spent the time and money to know they are not qualified.
After my failed attempts to find a good indy guy, I went to the dealership here. Yes, their labor is more expensive but they were able to fix the problem I was having. They fixed it and for a lot less than the other guys when you look at total cost and not just per hour labor.
In Miami, the only place to take a Porsche, is the Collection in Coral Gables. If anyone is interested in the places not to go, I would be happy to provide the names, but I don't want to blast anyone in public. It may be that I was the only one to have problems with them.
I cannot tell you how happy I am that my check engine light is gone for good (I hope!)
