EGR

Can the EGR be removed? Are there any bonuses or down sides to doing this?

They can be blocked, it's been done more than once. There are some potential downsides - search the past posts for particulars.

My EGR valve was not functioning. When I fixed it, the part-throttle pinging I had got much better, and my gas mileage went up by 2+ mpg. It is closed at WOT, so there is no performance loss either. For these engines at least, EGR is your friend!

100% correct! Plus, if you live in an emissions testing area that measures NOx emissions, like most IM240 type tests do, you will flunk without a functioning EGR system.

What mods? Main thing that will make the car flunk is a big cam. I have heard that people have trouble passing an IM240 type test with the A237 cam, but as long as you have a relatively mild cam, and everything else is working properly, you should have no trouble passing the smog test. Both my TC and Tbird 5.0 are fairly heavily modded, and I have never flunked the very strict roller dyno IM240 type test we have here.
