GAMI claims something else is going on. Fuel from the upstream injectors
is leaking into the downstream intake ports, making the downstream
cylinders richer than the upstream cylinders.

They can claim anything they want - but if what they were describing
was real, the coke bottle test would show it and adjusting the
injector nozzles would fix it.

The coke bottle test won't find this, as it is an artifact of the way air
flows in the intake manifold. And adjusting the injector nozzles is what
GAMI is doing. By making accurate injectors designed for each cylinder all
cylinders provide the same power.

snipped....

Do they provide the same power or do they provide the same air/fuel
ratio? I don't believe that they can do both. If they are providing
the same air/fuel ratio to all cylinders the power that they develop
will be dependent upon the volume of air that was getting to each
cylinder. If all cylinders are providing the same power, then they
must be receiving the same amount of air, which is not the case with
most aircraft induction systems that I've seen (not that that is a
lot). Not an expert, just curious and want to understand the
situation correctly.

Same mixture.
