I run 16 Holley injectors and am working on a project with 16 250pph AFIS injectors. Apparently they’re new on the scene. This guy switched from Billet Atomizers to these. https://www.hploil.com/afis
Wow, those are nice and $$$! I’ve looked at the Holleys also and their pricing isn’t too bad but they are low-impedance and won’t work out of the box with my Megasquirt.
