I tried to change PID in the FTDI chip (R232R) through FT_Prog. It was working but after it I found that Windows 7 automaticaly reinstal the drivers for USB device, not FTDI device. So I want to change back PID to default (6001). The problem is that I can not see this device in FT_Prog app because it has different PID number. I also tried MProg but with same result. I also tried reinstal Windows FTDI drivers manualy, but still can not see FTD device in FT_Prog. I actualy do not get it why is possible to change PID, if you cut of the communication with FT_Prod.

Ok, finally I foud a solution. Thanks to Preston. I just make a copy of default Windows FTDI drivers, open FTDIBUS.inf change PID number from default 6001 to my 6005 and just make manual instalation of driver. It is working now and also I can connect to my FTDI chip with standard FTDI tool FT_Prog. So with this I can simply create my own drivers just with my combination of VID and PID. More information in technical note from FTDI TN_104.
