So the engine running pretty good. No reason to suspect anything. My AI had me do a GAMI lean test to get a baseline on the engine. The results have my AI and Savvy scratching their heads.
#1-5 all peak within .75GPH of each other. #6 peals about 1.1GPH more than the last of 1-5. They say it looks like an inverse induction leak and can't figure out how that could happen, unless 1-5 were experiencing exactly the same issue and 6 is normal.
Basically, it appears that #6 is rich when but only after you start leaning. During normal cruise leaned ROP all EGTs are usually within 50F or so. When doing the lean test, all eEGTs converge at about 13.2GPH, which also happens to be right where I usually cruise.
Has anyone seen anything like this? Is it something to worry about? Savvy said it looks like an intake blockage on #6 but could conceive of how that could happen.
