Well I found a solution ... looks like you have to add or subtract from the base value.
cvaradd g_fov 20 ... so now the fov will be 100
cvaradd g_fov -20 ... so now the fov will be 60.
You cab do this from the console, but some people are saying is disables steam achievements if you do (not sure) so right now I'm doing it through launch options in steam. I tried adding the command through the default.cfg file but that didnt work.
To do it through the launch options ... +cvaradd g_fov 20
you cool thing is that the adjusted fov even at 100 doesn't look "fisheyed" it looks pretty good

here is the steam thread where I learned this.
