Code 32 on an '87 V10 305

Thanks for all the information.
I am pretty sure that it is attributed to back pressure with the exhaust. The exhaust is not a complete factory 2-1-2 system, so I presume that the back pressure could not possibly be correct for the original EGR valve.
I was intending to replace the system with a true dual system, so what would I need to do with the EGR then?
Leave the EGR as it is and make friends with the warning light?
Or is there some way that I replace the EGR to be correct for a dual system?

I was sweating the warning light being on, but now that I understand it fully, I am less concerned with it.

Very old thread.....But was wondering if anyone found the answer to this? I have the same situation. No light. Installed true duals (with H-pipe) and now the light pops on. Pulled the EGR and it looked perfect (35K mile truck). Replaced the EGR any way and the light still comes on so I'm assuming its a back pressure issue. Is there any fix to this other than getting a new chip with this EGR check deleted? Thanks in advance.

Mine did this when I put headers on. Finally just bought a modified chip from Brian Harris at tbichips.com. I can’t remember exactly what he did but the check engine light doesn’t come on anymore.

Did you see much performance gain out of his stage 1 chip other than the SES light not coming on for the EGR?
