EGR question

Thanks AJ, I understand all that and made sure everything was working as designed as I chose inadvertently to be a slave to this California smog state by attempting to get this 82 truck back on the road. I searched for 5 years to get all NOS smog crap on this with only the amp not replaced. All vacuum pods were tested, EGR pintles move (even without the amps help on this one) and this is even held to the lower FED spec as it was a mechanic lien sale within Cali making it one of the few ways to actually register a FED car in Cali and still use the FED smog levels. I had pretty good results extending the pintle on the EGR by unthreading the tip and then locking it with its locknut ( a very useful feature on this brand) making it open later. Once I get it back together Ill try and make a video of the amp behavior to share and discuss as the same system was industry wide about 76-84 with 84 being the most involved on this platform, then they went with a new design. When I got the NOS carb, it passed with flying colors. Even the smog tech was surprised how clean it ran but then it lost a head gasket and sat.
