[SirDigby]

I have looked into this thing before. does anyone use it?

I was looking at it again, and reading the mixed reviews/opinions of many other people on many other vehicle forums and have come to the conclusion;
some people see it as a waste of money because it really does not do anything but modify the acceleration curve and all you need to do is press the pedal faster. people that have paid $300 for it say they love it and it's the best thing ever.
the reason I am interested is the valet mode and the pedal lock out security feature. I really like that idea of locking out the pedal electronics so I can warm up my car legally in the mornings and leave it running without worries. when I take it to the dealer, I can set the valet to 35%! HA!
