I forgot one thing that TButtrick bought up
in years pasted company sold system that where not street tested or complete. I think the new companies sell a system that it tested and proven to work.
Components are a higher quality and matched to work with the whole system. Computers (processors) are much better and cheaper.
I think the standard fuel injected system is $3000 to $6000. Which is twice the cost of a carb'ed setup.
I think the cost is justified when you raise the hood and look at what appears to be webbers. And it has all the performance and street ability of a new car.
I think I have died and gone to car heaven
see ya on the road
