TCM "Position Tuned" Nozzles
Just got a new TCM engine? Happy about having their new "tuned" nozzles? We get calls here everyday from people who want to order GAMIjector® fuel injectors because they're just not happy with the new TCM set. But don't take our word for it, see for yourself with actual flight test data that was submitted by some of our customers. We'll let you be the judge.

We have three 206's with the Atlantic Aero IO-550N modifications installed. These engines come from TCM with their "Position-tuned nozzles." Unfortunately, we did a GAMI test on our newest installation and found a 1.6 gal/hr spread between the leanest and richest cylinders. We confirmed the nozzles were in the correct positions as per the part numbers.
Do you make nozzles to fit these engines? How do they compare to the TCM nozzles? I think the base hex fits a 7/16" socket rather than a 1/2" socket. What do you charge for a set of six nozzles to fit this engine configuration?
GAMI
We hear that all the time. We do make nozzles for that application and we can get that spread much closer. The list price is $799 and that kit can generally ship the same day you order them.
