How about spending 200 seconds (or less) lowering your idle instead?

The ECU gets a signal from the brake light switch. If the ECU senses IDL from the TPS and Brakes, it checks the RPM. If the RPM is over 1100, it cuts the fuel injectors off. When the RPM drops below 800, it turns them back on. This can cycle repeatedly if your idle is too high, and it would look like 500-1200 rp0m surges... About one per second.

Lower your idle to 750.
