The patented system of the optimized fuel injection nozzles uses much closer manufacturing tolerances. You now get injection nozzles manufactured specifically for each cylinder. Opposed to the original engine manufacturer's nozzles GAMIjectors take into account that each cylinder normally runs at slightly different parameters, which now have been adjusted for a much smoother running engine.
Many aircraft owners have not discovered this problem until they bought a modern fuel flow computer, showing accurately those imbalances of unmodified engines.
With GAMIjectors you get to save fuel due to the fact that you can now lean your engine on the lean side of peak. Your engine also runs smoother and is operated at lower temperatures. The temperature distribution in your engine is more even, which probably extends your engine's life time.
GAMIjectors are available for almost any fuel injected Teledyne Continental or Lycoming engine. If you wish to check the certification status on a particular engine type, you can download a Microsoft Word document with our complete certification list here
