Oil weight is based on engine tolerances and clearances nothing to do with forced induction.
The only time you should go up a weight is if you have oil overheating problems and then it should be a temporary band aid until you get a proper oil cooling solution. In extreme circumstances no amount of cooling can keep up so you may go up a weight.
The idea heavier weight oil is somehow always inherently better is foolish.
If so then why stop at 5w30? Why not 10w40 or 30w70? What makes 5w30 the magic weight? Heavier is better right, so put some 70w90 in.
But wait so then what makes 0w-20 the magic number you ask?
The engineers who speced, designed, built, and tested the engine determined it to be the ideal weight. So unless you know something an entire team of highly trained, skilled, knowledge expert engineers who built the engine don’t. Why wouldn’t you stick to the recommended weight oil?
Also keep in mind especially for a daily most engine wear happens at initial cold startup, where 0w-20 is far superior.
