I was looking into the code and i want to set congestion window size manually, so anyone knows where i can set it?

Congestion window is managed by a variable named cwnd in struct tcp_send_vars (see tcp_stream.h). It's finally referenced when sending packets at FlushTCPSendingBuffer in tcp_out.c. Just search with the keyword cwnd in mtcp/src/ for more details.
