EGR System Facts

You really don't need the EGR system and removing it removes weight from the vehicle as well. And that's good for you gas mileage, so saves the environment! Yeah right ;-) Note the EGR system only limits the NOx gasses on idle.

A six pack of beer weighs more than the entire EGR system, so NO better fuel economy gained.

The EGR system DOES NOT operate at idle. Please read and learn from the sites listed in my previous post.

A properly functioning EGR system WILL help comtrol engine pinging under load conditions. (I run 15* timing)

But of course pinging can also be controlled by:

1) Stay off hard accelerations (why have a supra, then)
2) Run premium fuel, and probably octane booster (cost more $$ to drive)
3) Set the timing back from 10* to 5* (or even 0*). (= Poor MPG)
4) Knock sensor detects ping, then computer retards timing (=poor MPG)

And what is the purpose of the EGR anyway??? It lowers the peak combustion temperatures, which helps prevent the creation of NOx, (which kills the air). And Thus Cleaning up the air WE breathe.

Without pollution controls the air will become so polluted, WE (animals) won't be alive more than another 100 years. Of course all of us reading this will be dead, but what about our children??
