Wow, you guys are amazingly trusting. For all you know this could be the electronic equivalent of a rag up the wastegate. Getting more HP from a turbo engine is relatively straightforward. Getting more power while preserving reliability, economy and driveability is a little tougher.
I have a very hard time believing you can simply liberate an extra 40 or 60 horses without doing a lot more than a flash tune. BMW adds 20hp and requires a whole lot more cooling for example.
For me at least, driving a car with a flash tune would feel like driving without insurance.....pleased in a small way to be saving money but perpetually scared to death that something bad happens
