Positive / Negative EGR Valve Number Needed

Hi, I got the common code 32 after installing true dual exhaust on my L03. I was wondering if anyone has part numbers for either a negative valve or plain vacuum valve that has worked for them. Thanks,
Adam

I haven't swapped to true duals or anything, but I bought a replacement EGR valve for my car not too long ago. It is a negative backpressure EGR valve, and it's AC Delco part number 214-5575 and GM part number 17113496.

Thanks guys. Ya I looked at that picture in my fsm. The egr and solenoids in themselves work, but the exhaust is not allowing them to do the correct thing in OD. Thanks for the number, I'm going to go check it out.

Well, I finallly looked closely at my "stock" egr valve and the GM part number on it is 17088125. It is a negative egr valve. The motor is an LO3 and according to ACDelco.com, the part number is a little different. Well I guess I will have to check my egr solenoid and intake passages now. Or try a different valve for my low backpressure dual exhaust. Any other ideas? I've already tried a '96 Z28 Camaro negative backpressure egr valve and that didn't work.
