What for?
There are seveal "tricks" for specific purposes.
Alter air temperature readings
Change air flow readings.
"Clamp" the O2 sensor reading
These really only work for/during open loop, or for a very short time in
closed loop, since the O2 sensor is going to cause the ECU to adjust the
mixture in closed loop. The O2 clamp has some longer term possibilities, if
the "rich lean" change is enough to fool the ECU. It may also be necessary
to alter the second O2 sensor signal.

The usual thing is to fool the ECU and add more fuel with a timing retard as
well.

It's likely that springing for an aftermarket ECU is in your future.
