@gunrunnerjohn posted:There are only two upgrade kits, one for diesel and one for steam. Obviously, you get the one that matches what your engine is.
You can load any PS/2 3V sound file or many of the PS/3 sound files into the steam kit, and the diesel kit accepts any diesel sound file.
which kit would you recommend for subways ? the obvious choice would be diesel but will the diesel kit accept subway sound files thanks
