911 SC track optimization.

Have now decided my 1983 SC will be exclusively a track car, so no more smog testing! Already has racing exhaust with no oxygen sensor. Questions: what parts, if any, can be decommissioned to gain engine performance; 1) frequency valve, 2) oxygen sensor control unit, 3) oxygen sensor power relay, 4) cold acceleration control unit. If all of these, disconnect engine fuel injection harness connection?
Will welcome any expert advice.

I would ask in the technical forum, because there is a lot of experience there with this sort of thing.
