If it is just a TPS (Throttle Position Sensor) adjuster - it is useless - then all it does is shorten the travel on your foot to get a certain TPS reading in the ECU - then I totally agree to save your money and "just step on pedal harder" idea.
You could do the same with a cable - just put in a shorter cable cam, so that 1cm cable turns 10deg more...
Sure your car will feel more twitchy - like getting into another car with low clutch take-up makes you jump the car a bit. If you paid for it, might as well try it... Let us know...
