Hi All,

I am really looking into converting over to an EFI system and wondering if anyone has experience with any of them. Professional Products Powerinjection 3 seems a good choice but I have read some complaints about their after purchase customer support. The EZ-EFI or the MSD Atomic EFI are also possibilities. Currently a Holley Double Pump 750 with return pressure regulator.

Any help is always appreciated.
