A power plant is what it is. Nothing more.

They decided to "spruce it up" by tweeking the throttle curve rheostat/potentiometer/whatever so that 10% throttle becomes 25% throttle.
A little gas becomes a lot of gas.
(oooh look at all this powah!)

I lube the cable and butterfly and OEM air filters peddle not sticking etc but it sucks in the wintertime on ice.
Just another stupid electronic thing to have to have to out-think.

I remember years ago, around 2000, I travelled a lot and rented cars. 2 locations, same week, 2 different monte carlos. One car, stop the car, let off the brakes, and floor the gas and the car would spin the tires. Tons of off-the-line power, but then felt pretty gutless at upper RPMs. Next location, another Monte Carlo. This one, try the same thing and it's completely gutless, but if you keep the power on, it really "kicks in" between 3000 and 6000 rpm with a huge surge. Both were 3.8L 6-cyl, IIRC. I suspect most of the difference was in the electronics.

My boxster has Sport-Chrono. Hit the sport button and the off-idle acceleration improves, but I think that's mostly because the throttle pedal has been remapped, not because there's any sort of power bump.
