STR button on the 166 3.0 V6

I was wondering the other day what actually happens when the 'STR' button is pressed on my 3.0 V6 Super...

Certainly, the throttle response is sharper, but the ultimate performance of the engine seems to be the same as when it's not 'on'.

Does the STR button actually change the power/torque characteristics of the motor, or does it just increase the throttle sensitivity?

The STR sharpens the throttle response time, opens much more sharply, there are different settings within the ecu too, from economy to sports, varying the response from the engine, a bit like chip tuning, but obviously not differentiating that much in power output. Hope that clears that up for you!
