I never modified things on my car calling for this, but I believe ESS offers custom maps free of charge as well? I remember reading so on their website. Of course if you buy a new car, then that is a different case.

BTW my general opinion is this: You will get a high quality tuning product from any tuning company that also offers engine/throttle response and perhaps DCT optimization. Because if they can make optimizations in these areas, then they probably know what they are doing. And to such tuning companies, simply increasing boost targets and HP should be the easiest part.
I wouldn't be too concerned with who is spending more on marketing/fancy websites or choosing the right pricing strategy. The best engineers are sometimes the worst business people.
Finally it is also worth following this open source project to learn more about what a software tuning product actually is, and what you pay for:
