Thanks, Don. Does your injection go into the exhaust manifolds or directly into the cylinder heads? Was your truck TBI from the factory or carbureted?
When I challenged the guy on the phone at MSD questioning why then does the ECU have a setting for Air Pump Equipped: YES/NO, he said this is for when the air injection is after the O2 sensor but before the catalytic converter(s). Uh? Did that even exist on a '75-'87 GM motor? Maybe a TBI equipped model...
