Gerard -
Have you attended or taken the on-line course: Advanced Pilot Seminar? It is the bible, IMHO, for running an engine lean of peak. A couple of questions: Did you ever run a GAMI Lean Check? Based on that did you install GAMIjectors if the test and the folks at GAMI advised to do so? It may be that the mixture for numbers one and three were in fact running very close to peak egt because of the mixture imbalances between the cylinders. What were your CHT's? You may want to download the data from the EDM 700 and have it analyzed.
Hope this helps you in the future.

just burnt out the exhaust valves on 1 and 3 (got 900 hours on my 0-320)
the shop reckons I'm running it too lean. I had an EDM 700 installed last year and follow the directions for best power-usually gives EGT 1450-1500 and 31-32 Litres per hour
what say y'all
