you'll need to have the EGR tuned out if you haven't already along with the AIR system... as for the intake you'll need to either cap it off or get a LS6 intake...

^^This.

In getting it Tune, check out TunebyFrost.com He is our resident tuner. Really great service. He is also a member and a Sponsor of the site.

Pajeff wrote a good thread about removal of these systems - http://www.ls1.com/forums/showthread...=secondary+air

Can I just cap it off and not have it tuned?? Would that mess anything up or make it run bad?

Your SES light will stay on. And I would highly recommend at least pulling the fuses and relays - as there is no need for them to be running. You do not need to have it tuned though. If you plan on doing more mods then it would be ok to wait to have it tuned. It won't hurt anything if you don't - your car just won't be running optimally until you do.

Thanks for your help guys...I only have 1 more question....Any ideas on how to plug the intake?

You can pick up a blockoff at your local GM dealer, or get an expandable freeze plug from your local auto parts store.

To do the EGR delete. The air system has to be the delete?
Or you can just delete the EGR

**Cutlass** · 08-03-2010, 03:43 AM

nope. they are 2 separate systems and you can delete either one by itself or both together

Thanks for the reply
So on mine. I think I'm gonna have to delete the EGR. Do I just remove the egr from the engine bay. Or is there anything else I have to do ?
Fuses? Or I can just leave em there
I'm in Cali. So on emissions time I have to put it back

1 3/8" expandable freeze plug for the intake.....couple of bucks at any parts store. There is also an EGR timing adder table that really should be zero'd out to keep you from seeing tip in knock retard. Talk to Frost and let him know about your emmisions situation and I'm sure he can hook you up on the tuning side of it.
