You start learning the concepts before putting them into practice. This next part is going to sound condescending, but it's not. Pickup a book on the principles of forced induction internal combustion engines and learn a bit of the basics. Then start reading the tuning wiki. I don't think you're quite ready for this stage however as you are already asking the wrong questions. Before starting this process, you should have a goal in mind. Ex: A turbocharged engine running x octane will operate most efficiently at x lambda. How do I achieve that? Ex: Here is my compressor map, peak efficiency is at x. What do I need to do to achieve this?
Then, use the tools here to reach that goal.
Or, just jump right in I suppose. It's incredibly hard to disable enough safeguards to melt an engine on stock hardware. I personally would choose the former however
Welcome, and good luck.
