GAMI Injectors

[n86121]

Turbo 337D

On my last annual wallet-ectomy
both fuel pumps were bench overhauled with precision.
Rear throttle housing was also leaking, so it also got the treatment.

Suffice to say, whole fuel thing gone through.

My rear engine had two gnarled injectors from prior annual, that needed replacement.
TCM was back logged on injectors for months, but GAMi available next day
Decision made, went to set of GAMI

Given both precisely bench OH fuel pumps...
the two engines would otherwise seem well matched

No fancy engine analyzer.
Never saw the need.
Fuel not a major lineitem in my life, and $10,000+ cost to install F&R buys a lot of fuel.

I just find the leaner EGT, set it to 75-100F rich of peak,
then match fuel flows between engines, to keep my shadin having same flow rates F&R.

That said,...

The rear GAMI equipped engine needs almost no mixture adjustment throughout its range.
Really, almost zero. Nada. Zip.
It is as if the full range is just super precise and super narrow, full range.
While the rear I still have to fuss with mixture to get similar flows on front.

So next wallet-ectomy, going to add GAMIs on front too.

Thoughts?
