What's the frequency of the 2011 GT500 MAF?

I have a snow performance water/meth injection kit I'm putting on a 2011 GT500 controller and their progressive controller box is voltage based but I hear 2011 and up GT500s use frequency based MAF sensors. I called Snow and they have a frequency based controller box they build for GMs that they could send me but they don't know if it works on the Fords or not. They said their box is programmable with a low of 3000 hertz and the top side is 14000 hertz. Anybody know what frequency range the GT500s use?

Good question as I was looking into the snow meth kit also, not sure about the controller either. We're did you put the nozzle for the meth, near the throttle body or right after the maf? Please post a pic when your done. Thanks

I put it in the intake plenum opposite the nitrous.

Just need to figure out the frequency so I can see what controller box to use.
