Used it today and it's brilliant feels smoother than normal i did make a pop for fun but not going to do that too often because that what break/bends the rods.
If you think about it your putting massive load on them when you fill the cylinder with excessive fuel and then ignite it its going to break something, your really making a bomb inside your engine.
Not tried launch control yet as it's set way too high rpm, plus i'm still on a standard clutch.
