LML,

On completion of a GAMI test recently I noticed that when slowly increasing fuel flow from very lean to peak, cylinders 1,3,5 all reached peak first.  Then going backwards, from very rich to peak, 2,4,6 peaked first.  I have GAMI injectors and its a TSIO-550X (bigger Malibu turbos is only difference from an E) built by Barrett in OK.  Any ideas as to what would cause this?  I have repeated this multiple times and can’t figure it out.
