I have a Superior IO-360 on my RV7A,a Dynon D180 and a Generation 3i electronic ignition. I cannot go to lean of peak. The engine quits almost after reaching peak. For example 8500' 22 MAP 1479F at peak EGT and 10.7 GPH. My EGT probes are all 4 located at 21/2 inches from the port. The GPH given by the EMS is accurate up to 1/5 of a gallon. Is it a problem of probe location ? fuel injectors or else. Some told me that the probes are to far away from the port by at least 1/2 inch. Any solution suggested
