Music Today we've got our Stage 4 Cuckoo for our VF2. Again, they're probably one of my favourite models. These things really light up and they probably should have come from the factory So we have our Ramjet 3 with the math in it. It looks ultra factory. It's got our triple step headers on it and full system. We'll run the dyno and show you what it can do. They're pretty cool and they make good power. If you've got one of these, I suggest you bring it in. We'll show you what's going to happen. Okay, good power for the LL3 M6. So that's a good testimony of using the right part. So it's got our best air intake on it. Ramjet 3, it has the triple step headers that the customer upgraded to. All the right components and that's the result. 308. 6. So as you'll see, it's a good result. But what will show you as well is everyone of our cars have come on the dyno. It's not just a drop in tune. A drop in tune might work for general motors when they want to be safe. So we custom tune all the readings can be a little bit different sometimes. Some of the internet worries j Depending if you've got air leaks or whatever it might be. We've done t But what we'll show you. Okay, in the red one is when we first rounded up and done. And you can see the lambda is fairly different. 0. 9, 1. 8, 0. 7. That's the difference in engines, cars, fuel systems, fuel injectors. So what we've done is we've obviously custom tuned it to to suit t So that's what we do here. Can we do my auto tunes? Yes we can. They'd probably just be down a couple of percent for that safety margin. Here we're safe, but it's custom tail made to the car. That's why you bring it here. Some of the t Some people question and go, oh, it's lean up the top or it's doing certain t What we'll show you here is, depending if you're getting onto the rev limiter or not. The other one here. Okay, I purposely here pulled the rev limiter down. And you can see here, as you go, t Look at it, look at it, it's taken off. That's the rev limiter coming in and cutting the fuel and done. So what can happen is if your rev limiter is on the roll over, you can actually see it. Sometimes you might get tricked a little bit by the fuel, but realistically it's the limiter starting to come in. And it depends how aggressive it comes in. And there is figures you can change it in the rapid rate of acceleration as well. So it's pretty technical. Sometimes what you see on the graph, you can't just go and anticipate, go, that's what it is. Because there might be other factors that So again, that's a bit of insight for GM Motorsport Straitos VTV to just show Two, if you're looking at somet So we try and tell you why it might be. You can't just j So bit of an insight. We're professionals at it. We've done it for a long time, so we do know what we're doing. Sometimes when you see somet It might be a sensor, it might be an air leak, it might be positioned, it might be a muffler. It could be so many t So bit of a background. So hope you Thanks guys.
