I started this thread a couple of months ago, when I noticed that my
car's pedal did not pull the throttle far enough to engage the WOT
switch. I jimmied it a little to make it work, and the results were
remarkable. It seemed like I had 20 more HP. Maybe I did since I could
now get the throttle open more than 50% of the way. The drawback was
that the secondary port opened too quickly, resulting in a very touchy
pedal feel.

Later, my mechanic fixed it correctly, and it is wonderful. Smooth pedal,
and all that power still there.

Check your cables for slack!

Only my cat shares my opinions, and she slacks off a lot.
