Do any of you guys that have removed the EGR system, have any of you had problems with pinging?

Default Egr Or No Egr
Was wondering what if any horsepower difference there is between the non egr vette ls6 intake and the Slp egr ls6 intake? I have a 2000 Trans am, i could delete the egr, but if the difference is small enough its just easier to use the slp.

I figured it would throw codes but I've had mine reprogrammed so now I'm good to go. The intake was nasty though, need to clean it out now.

its probably minimal but it sure cleans up the engine bay and saves a handful of weight off the front end of the car.

I disagree. I think it adds power on cammed cars, at least if you have one with a lot of overlap. The cam causes dilution of the mixture, adding in EGR on top of it may dilute the mixture too much. It may sound like BS, but I felt a difference. And I was not expecting to.

what do you do with the wires that go to the EGR after you remove it? trace them back to the computer and cut them off or what?

Most just zip tie them out of the way.

Goodness, don't cut them off! If you ever have to put it back on, you will be in for a ton of trouble. Wrap electrical tape around the plug end and tape and/or zip tie it to the closest part of the wiring harness on the engine.

... make sure you pull the two A.I.R. fuses so that thing is dead and doesn't blow hot air under your hood.

You'll have stronger carbon emmissions coming out your tailpipes. This, alone, won't cause you to fail emissions testing, IMHO. However, it threw codes on my car immediately, so, if you go with a bigger cam, it would increase the potential to fail testing.

As for the wires? I used clear duct tape to seal the connector's and did what WILWAXU said ... zip-tied the wires out of the way.

I know what the EGR tube is, but what are you referring to when you say "A.I.R."?
