A TBI system even with the best electronics and software isnt going to be much better than a carb.
Fuel distribution, fuel atomization, fuel puddling (wetted walls), Airflow (air heavy with fuel), etc.
Port injection gets the fuel where it needs to be and the manifold runners don't have "many folds" to make room for a carb or TB.
Exactly. A wet manifold will never get you the MPG and response of port or DI....But, it works fine for the vast majority of car enthusiasts that are not driving competitively, which (I believe) is the main target of these 4150 based, self tuning, "EZ" systems. I have installed and driven MSD, Holley and FAST versions of these and they make a nice upgrade for the guy that just wants to enjoy his car with an old engine in it. The self tuning is actually very good at it's job in most cases as long as you have the system installed correctly, which is harder than the advertising implies.
There is a big difference between the perception of the "best" on the internet and what actually works for
most people. It's like chasing the perfect roll center...diminishing returns after a while. I'm all for high standards though and have built and tuned many modern, forced induction, standalone powered cars also.
