Does Appvance integrate with SpecFlow for Performance Testing?

I have an assignment to do rigorous performance testing of my .net web application, talking to field devices (typically fare vending devices and traffic cameras) via a Windows application (Service). I also may have to do some stress testing. 

Can I can use the Appvance test tool and integrate scripts generated therein with SpecFlow where functional test scripts are also maintained to have a one-stop test bed sort of solution?

Thanks
