i dont think it's an equilivent  measurement;  .
egt s are common on light aircraft for setting mixture  but they dont 
have to pass emmission tests"yet"   ie   peak egt- 25 to 50 deg rich 
for power  lean to peak  for economy  thats what my instructor told me
and  never lean below 3000 ft or at maximum power only at cruise.
