I did back to back quick fuel vs. FAST TBI self learning years ago...It actually took me a while to get the FAST system to the same ET as the carb. Got to pick the right WOT AFR and get the squirter shot right.
When I was done, they were within .03 of each other.
.03 does not seem like a lot when you consider the extra dollars and parts required for EFI.
But it could be the last time you have to mess
with it.. I've been real happy with my Holley
EFI multi point after I made some wiring changes
and I do love the aspect that if I want to change
something its just a few clicks on the lap top
