Yeah, a probe in all four cylinders would be interesting.  I think EGT is
more informative than cylinder head temp.  I always installed a pyrometer on
my VW turbo diesels, I don't think it is nearly as useful on the WBX though.
I have one EGT probe in my WBX.  The problem with one probe is that the
point in the exhaust system where all for cylinders come together is a fair
distance from the heads.
I found out what I was looking for within an hours driving time and have not
needed it since.  I was looking to see if there was any difference between
burning gasoline or propane.
