adding custom PID for reading MAF frequency in Torque app?

Figured I?d try and post in here since the other section doesn?t have as much traffic. *mods if this isnt the right section please feel free to move it)

Currently tune via HP tuners for my 01 LS1 camaro. Whenever I don?t tune, I just use my torque app to scan. What I noticed is that the app doesn?t have the PID for the MAF frequency, but just the MAF for g/sec. I was curious if anyone knows the PID formula to add a custom PID in the torque app to display the frequency (hertz) range that would go along with the g/sec PID that?s pre-loaded in the app by chance? That way I at least know what frequency range I may be leaning from my wideband when lugging up a random hill etc.
