Default cheap power boosts?

I was reading the specs on the engine coolant temperature (ECT) sensor
(by the radiator hoses) and on the intake air temp sensor (on the air
filter housing) from turboninjas.com/camry/eg1.pdf

Then I saw this: http://autorepair.about.com/library/faqs/bl250i.htm

Looking at the sensor graphs, I'm guessing that you can fool the ECM
into thinking it is about 0 degrees F outside, and boost the fuel
mixture, by putting one 10k-ohm resistor in series with the ECM wires,
and another 10k-ohm resistor in series with the IAT sensor.

I haven't tried it, and gas is kind of expensive nowadays to try it,
but anyone else gave it a try?

I'm tempted to try it on my 155k mile car, but I think I've outgrown
the days of abusing the car... ;-)

Whats the point, you will make it just run rich like with the choke
on, It might even not fully rev, you wont gain power and will just
foul plugs, carbon heads, and shorten the life of the cat converter.
