Hello
The TCP part is hard to say without a better or deeper knowledge on the application, just like that I would suggest to try webservices only or protocol advisor, saying that this is TCP is not really helpful to understand since Web is TCP, same as all other LoadRunner protocols.
try that and let us know how it goes.
