Headers 1990 iroc z 305 tpi smog pump
Hey there you guys, I have a 1990 camaro iroc z with the 5.0 tpi. I bought headers off summit racing. I noticed on the stock headers there’s extra lines that go into the smog pump. So my questions are, if I remove those lines and delete the smog pump. Would I have to mess with the egr valve? I know they sell kits online with a plate to block it off. I seen a video of a guy on YouTube that does it but burns the chips. Can I remove the smog system without having to touch the egr valve? And having to tune the ecm? Nobody around where I live has a tune to burn chips anymore. Can you guys point me in the right direction? Thank you in advance.

Air pump and egr are two separate emissions systems. You can disable the air pump in the tune but won’t have issues. The egr if removed you will get a code 32.
