If you elect to run an aftermarket ECU or a modified OEM ECU you can get a nice starting point in your tune from the self tuning capabilities that the system has, if it has them. Beyond that you will benefit significantly by tuning your system for your engine / car / application.

Just like putting on a bigger carb and having to re-jet the carb for you car, EFI is the same. If you think you can pick it out of a box and begin using the car w/o a tune you will be sadly disappointed.

The big benefit that EFI offers is absolute control over all the fueling and timing variables for the engine. If you are uncomfortable with that level of responsibility or if it is a bridge too far, you have three choices;

⦿ go back to a carb,

⦿ use a self learning unit (to the extent it learns),

⦿ tune the car your self or get someone to tune it for you.

BTW that last option requires dyno time for the calibration process to be done correctly — and I should have added someone who actually understands the tuning process.
