Question for everyone, though...I'm not running an O2 sensor in the bung. Should I be? Does this affect the performance of the SCs? I figured with no cats, the 02 sensor is not necessary either.[/QUOTE]

I have been told by everyone I spoke to who is knowledgabel to use the O2 sensor for the CIS System.

RoW SCs have Lambda system removed, smog pump installed to be federalized in U.S.

My O2 sensor is still there but not connected to anything.

I just purchased a early set from a 73 with factory muffler, should I expect to get the same type of gains or do they have to be SSI
