Question About an ILS approach

I have Kai Tak (Fly Tampa) installed and, thanks to folks here, can also use my 744 and MD-11 to fly the IGS13 approach and various STARS.I have TrafficX installed (JustFlight). I also have a traffic.bgl file for VHHX that some kind soul supplied (sorry, I forget who).As you can see from the pic, almost all my AI traffic uses a path allowing a slightly wider turn for the 13 final approach.Which of the files I placed in the Navdata folder when setting this up, would I need to edit in order make that change?and errr.... how:-)
