Looking forward to the results. I hate driving my car in the emission test configuration because it won't get out of it's own way below about 2000 due to so little torque/power.

If you have an automatic it will probably not be as noticeable because the converter stall speed is probably about 2000.

I keep the shorting wire and short piece of plugged vacuum hose in the glove box. I install them the night before emission testing and remove them the moment I get home. It only takes a few minutes.

If you leave the OE resistor off the spark advance with engine revs will be the most aggressive. There is so much more low end torque that I can shift my five-speed at 2000. Fifth is okay down to 30-35 MPH, and around town MPG increased a solid ten percent.

This may not be achievable with an automatic because the moment you load the engine at low revs it will jump to converter stall speed.
