Happy to help everyone!
One thing I didn't mention in that post, because I haven't had time to test it and take photos:
The little rectangular platform that shorts to the shorting bars? It's adjustable up and down the bolt. If you find that you have to really mash the gas ("need to cut a hole in the floor to push far enough to get to full throttle... " type of thing..) that platform may be a little too low, and not quite contacting the shorting bars when you push all the way down.
I've had one or two pedals that have done that.
Alternatively, if it hits full throttle way before you think it should, it may be a little too far up and shorting before it's supposed to... just make sure you take a peek at the adjustment I mention in that article -after- any adjustments to the platform, one can affect the other adjustment.
This -usually- only happens when someone takes the whole pedal apart and re-assembles incorrectly.
