REFLECTOR: Running LOP

[Brian Michalk]

Well, they mean something.
Assuming the probes weren't "trimmed" to give even results and are 
reporting actual EGT's, then even EGT's mean even power across cylinders.

Uneven EGT's can be caused my two things:  Uneven mixing of the 
air/fuel, and uneven airflow to the different cylinders.  Cylinders that 
breathe better will make more power, and thus higher EGT's.

Different mixtures will result in peak EGT's at different temperatures.
Different airflow will result in different cylinder to cylinder EGT 
measurements.
