550cc dark red injectors what make?

[GINGA]

Anybody know what make 550cc injectors in a dark red colour are and even better what the power fc settings should be for them :?: as the ap engineering site is down at the moment

dont quote me but think the APEX are red "top" injectors

is it like purple? Anyways, if it looks like this; these are 550cc Mazda RX-7 injectors (5th gen) Sorry for the rediculous size, but if I make it smaller it's not easy to see the colour right
