LOLMesozoic, I want to marry you. Wait are you female??
This is exactly the information I was looking for. I attempted to do EFI on the cheap with an old Holley 950 Pro and throttle body. The results were mixed, little more power, less driveability, less gas mileage, and broken something in the engine. Most of that was due I'm sure to my lack of tuning knowledge with the system.
Anyway, I'm going to replicate your process on my 73.
Yeah, the '71-73 Mustangs make a good platform for EFI conversions. Minimum of fuss to get wired and cabled up. My next project on the car is going to be reinstating the A/C using a Sanden compressor retrofit, but all hooked up via the EEC so it runs like an OE EFI setup.
