New Holley spreadbore FI

General information there. What Holley efi, what year was it made? Early model? The Lenco is a racing trans suggesting a race car. The above Holley FInis obviously (IMO) a replacement style low power unit.

What does throwing belts have to do with anything? LOL!
Holley sent him calibration mods? These are self learning.
Your casting a shadowy doubt based off another’s experience of how long ago on a older system?

It was a couple years ago but my point is FI wont richen up with a instant load change you have to give it more throttle to get more fuel. Holley said it would work with his set up and they had all the engine and car info to give him a start point when he bought it. The only way to monitor load change is with a MAF sensor that's why cars have them for driveability. When I said throwing the belt off I mean blower belt, it would back fire and break the belt at $200 each and he went through 6 or more before he gave up. It was his driving habits, if he would give it more throttle while grabbing the next gear it would probably be fine but he was trying to not do that.
He spent a lot of $ and it was a dual FI unit on a 6-71 and 540 cu in.
