Perhaps or perhaps not Clinton.
I have a modicum of understanding of piston engine fuel systems, both mechanical and electronic.
It is true that manifold runners and other variables affect efficient and balanced fuel to each cylinder. This isn't just a problem for aero engines, think front and rear cylinders on a carbied V8 - Holley square bores overcome the lean running on rear cylinders experienced by spread bore carbs.
There are two issues when using GAMI PMA injectors:
1 Injectors balanced to each cylinder is a good thing
2 LOP - use at your own risk
BTW I cannot find a copy of the STC or it's FMS, would be interested in reading both.
