Gamijectors for SR20?

Does anybody know if Gamijetors are yet approved for the Sr20’s IO-360 ES? As far as I know, there is a general approval for Gamijectors on IO-360s but does the airframe or the combination of an engine with a certain airframe need approval, too? The standard fuel nozzles on our SR20 seem to be very imbalanced on our SR20, since we can’t lean any further than 30° LOP without rough running. Also Gamijectors aren’t too expensive so I think it should be worth the money, isn’t it?
