Mine has a power, normal, and snow mode. It's a blast to drive in power mode but after a quick dash I can literally see my gas gauge move a few notches lower.
Does your car have some type of "power" mode?

I can (and do) downshift to a lower gear for fun...

my computer has a turbo button. it turned from an pentium 75mhz into a conroe quad core triple-pumped FSB at 475 ghz with SDT- superduperthreading.

Same here.
My car actually does have a performance shift mode on the transmission, but it doesn't affect gas mileage that much really.
Yes ETC Power button on my Toyota Tacoma 4cyl auto. Electronic transmission control, press it and up shifts come later at higher revs. I use it when merging on to the freeway then turn it off.
Although not a true manual it does have a "manual" mode giving you electronic control over the shift points. Power mode is for a totally different purpose. It increases the air-fuel ratio with quicker and higher shift points. You can totally feel a difference in performance in power mode at the expense of gas mileage.
my car just pretty much has drive and reverse. sometimes if im lucky they actually work right. other times i can put my car in reverse, but it will operate in drive
If I take off my boost controller it limits me to 6PSI of boost. For further power reduction, I can pin the wastegate on my turbo open, so there will not be any boost created. I guess you could call that a switch.
My car has the manu-matic shifter... I can put it into manual mode and go through the four gears myself (without a pedal) and rev as high as a like. Not as good as the six speed manual version of the same car but it is fun at times.
now i may be wrong on this one, so if i am feel free to point me to a source. but wouldn't changing the air/fuel ratio cause the car to run lean (over heat the piston) or rich (waste unburnt gas) leading to no power improvements? now it may allow more fuel and air to enter the system to create more power and thus have to adjust the air/fuel mixture a touch (not too sure about this one as when the throttle is wide open it is sucking as much air in as possible and would negate this effect). The only thing I can think they do is if your throttle body is electronically controlled, they just change how it reacts to the accelerator pedal. That would be the easiest thing to do to make the car seem more peppy along with changing the shift points. they also may retard or advance the spark to get different torque characteristics at higher rpm along with changing the shiftpoints. i don't think there is anything they can do to "quicken" the shift, likely it is as quick as it can be in any mode you pick.
No, but my suspension has a sport and touring mode. The engine is always in power mode. Just hit the gas pedal.

Yes, it's called shifting into a lower gear.

He's talking out of his ass. The button on the transmisson only affects the transmission's shift points and downshift threshold, it doesn't make any alterations to the engine's mixture.
And yes, my car does have a power mode. It's called setting the boost at 15 PSI and flooring it.

how does raising (or lowering for that matter) transmission shift points affect air-fuel ratios?

My brady wagon has OD and D. Shifting to D yields more power for those long hill climbs. Does that count?
Yes I am the jackass in front of you dragging my 80" wide GM ass up the hill at 35-40 mph with the A/C going full blast while you cuss and curse because you bought a fun little sports car that would absolutely leap over the hill in a single bound if I would just use one of those pullouts and get the heck off your road. My head is getting a bit chilly; think I'll put my hat back on.

LOL
going from OD to D only stops you from going into over-drive. In effect, top gear ratio is 1:1. So you tend to stay at the rpm you are driving at. If at 50 mph you are say revving at 3000 rpm in D, the OD will be more like 2300 rpm; a noticeable difference. Being in your power band makes the car feel like it has more power, but it doesn't. It just revs into the powerband faster because you are closer to it.
My 1987 Crown Vic has the same thing. I usually leave it in OD, since it does nothing until 60+ kmh.

Yep! My car has three shifting modes for the automatic tranny: Drive, Sport, and Triptronic. "Sport" seems to be the quickest, as I seem to get a bit of lag when I shift it myself with the Triptronic clutchless manual.
