Yes I just purchased the pedal monster, I had been on the fence for months and was ready to go for the sprint booster but that banks video above really convinced me to go with the pedal monster instead.
The banks has more features too, it disables itself on reverse (currently not supported on Ram 1500 but apparently in the works), and you can trim out the throttle on low speeds etc. Just seems to be a much better and well engineered device.
And, it's made entirely in the USA (including the manufacture of the circuit boards).
I've only had mine for a week or so, works as advertised. Sort of transformed my truck (as would any device like this). I bought the standalone edition, pairs up via bluetooth to my android phone, works slick that way. Because it uses the OBD2 port, it knows when the truck is in motion and will prevent you from making changes to the settings while driving. They were forced to do that in order to get it approved in the various app stores, not sure if the other versions (which work with the banks gauges) have that limitation or not.
One constructive criticism I have for it is that the OBD2 cable plugs in the wrong way for our trucks. The cable ends up pointing towards our feet instead of the firewall, which means I'll probably always see a little bit of the cable sticking out from under the bottom of the dash. Small price to pay, there might even be adapter plugs that switch the direction of the cable around.
