 Okay, Mike is calling from Davenport. Go ahead, Mike. You're on Soil Talk. Yeah, guys. The engine isn't performing like it should, and I'm wondering what's going on. All right, a couple of questions, Mike. Do you have high porosity in aggregates? Is there a porous medium for gas exchange? I don't know. Well, hey, look, Mike, if you want performance, you've got to find out if it's good under the hood, huh?
