$3000 Tax Credit

I have to add something I overlooked -- someone brought to my attention today that a $3000 tax credit comes with hybrids. That helps the first year and cuts the time it "pays for itself" -- so it would depend on a persons tax return results...

I'm considering a all off system for my automatic subaru.
When slowing down flip the switch and cut off the signal line to all the injectors. At the same time it would need to turn on fake sensor signals so the computer thinks everything is normal.

Cutting back the number of cylinders seems like it would have adverse effects. My car runs like crap if it is missing on one or two cylinders. The car would likely run a little rich as the disable cylinders are pumping fresh air over your O2 sensor.
