 Some scan tools you can read it with, like a GM scan tool. But if it's under boost but not too far, it won't set a code. And it doesn't take much, like a pound, and it's just going to be weak. And the hotter it gets, the worse it could be. It sounds like you've probably got a turbo that's starting to bind up a little bit, and the wastegate's not working right, and it's just not spinning like it should. Because that's huge. Yeah, and I guess I forgot something.
