There is a similar thread running on this.
Bottom line, if you want it perfect, then it has to be PCV and Dyno.
Auto tune modules, where I am at least, have a pretty bad reputation for being sketchy. They are a great idea, but if they did what they were supposed to do, then all the race teams would be using them, and no one would bother with a dyno map any more, however in reality, from the people I've spoken to when researching this, they leave a lot to be desired.
