It is the sensors that don't like the lead in fuel. It shortens the life of the sensor. But, if they are not a permanent install (probe in tailpipe) then you should be fine. Double check that the lead does not alter the readings but AFAIK it doesn't, it will over time though and you will need to recalibrate the sensor more often.
The disadvantage of the probe in tailpipe is inaccurate reading at idle due to inadequate gas flow as the fresh air outside the tailpipe can get to the sensor. This is the same reason you don't mount a permanent sensor too near the tailpipe.
Sounds like you should get an Innovate LM-1, it has a proper recalibration sequence.
