I'll be doing this too in a few weeks.

what about the air pump under the ignition coil? should that come off too? And will I get any trouble codes from the egr actuator being unplugged?

Yes, I think you will throw codes for an EGR delete.

any way to avoid the codes?

Zap em with a tune afterwards or don't remove the EGR components.

OBD1 will not set a code if you remove the air pump but leave a fuse in the box for it and just have the wire hanging. Although when removing the air pump you are better off removing all that tubing and the bracket and the pump itself then plugging those fitting in the exhaust manifolds. Removing all these things really free's up usuable space.

Can you remove the EGR stuff but leave the AIR stuff, or do you have to remove the AIR with the EGR?

Can you remove the EGR stuff but leave the AIR stuff, or do you have to remove the AIR with the EGR?Yes. but I recommend removing them together and then paying the 50 - 75 bucks and getting them tuned out. For performance applications at least I think this is the better option.

Well, I just want to remove the EGR to get rid of the exhaust leak, not necessarily for performance gains. And I wasn't planning on messing with the AIR crap.

I absolutely agree on the usable space thing. Im pulling my heads and really wish I had more room to work. Thats the main reason im doing the delete. Just to free up some room while im at it and less stuff to mess with when I put it all back together.
BTW...how good is the performance gain form the EGR delete?

The major advantage to doing away with the EGR is if leaks and fails. The most likely vacuum leak area on a stock LT1 intake manifold is at the EGR gaskets.

Plus you really don't need it, the LT4 did away with the EGR. Infact GM makes the block off plates for LT1's intake manifolds but not the passenger exhaust manifold.
