I find it weird that the Explorer ST doesn’t have a boost gauge. Well at least not the 2023 model I test drove.If they include a boost gauge that's like the ones in other ST models, you're better off replacing it anyway. It's not a "proper" boost gauge and doesn't work very well.
I wasn't sure if the explorer did or not. My FoST did include one from the factory. I'm not smart enough to know why it's "fake", but I just know from what I've read on the forums it's not a true gauge.I find it weird that the Explorer ST doesn’t have a boost gauge.
