Having not played with any aftermarket TBI myself, I can’t say how effective those adjustments are...... “at the hit”.

With a carb, it’s a mechanical connection to the accelerator pumps.
Open the throttle, and while the lever is moving, fuel is coming out.

With EFI, the computer has to assess what the sensors are reading, and make the call to add fuel.

Perhaps the aftermarket has improved this characteristic over how the oem stuff performs in that regard.
Any oem EFI equipped vehicle I’ve ever driven has a momentary hesitation going from idle, or barely above idle, to wot.......with the type of rapid foot action you do when you’re trying to cut a light.

Perhaps the EFI footbrake racers will chime in with their experiences.

If you’re running a combo where you’re loading up pretty high against the converter, it’s probably less likely an issue.
But my car used to ET better when leaving slightly above idle.
