EGR needed?

[Bill Kerkhof]

I can't say you need or don't need an EGR. What I can say; I've put more than 60,000 miles on a properly tuned (calibrated custom chip) TBI 350 WITHOUT an EGR. Maybe someone didn't know they needed to use a calibrated custom chip when they ran a TBI engine without an EGR????

Where can I get custom chip you are talking about? And I assume the chip is the PROM from the ecm
again thanks to all the help
