I'm not thrilled with the pedal 'feel' of mine either, so I'd love to have a good solution to the problem. From the pix, you attached the cable end to the new bracket, instead of having it anchored on the firewall. I'm not seeing how that changes the geometry though... How did you move it relative to where it was, and why couldn't you do that when it was on the firewall? Is it just the stiffer foundation to work with (instead of the firewall) that makes the difference? I'm not doubting it helps...just trying to understand what the fix is so I can try it on mine.
@klean63 - the complaint is usually that it takes too much pressure because it feels like it's binding, and the pull angle on the cable end isn't great and doesn't give you the right leverage. Mine works OK through about 3/4 throttle, then it's kinda random. Sometimes you can get WOT, sometimes you get 7/8, etc. Others have said it's the stalk part flexing, and adding a lower mount point to the stalk has helped.
