Default If I'm replacing stock injectors with new stock ones, will I have to retune?

Title. Sorry for the dumb question as I'm fairly new to tuning / fuel systems. I have some reasonable suspicion that my injectors are excessively dirty or clogged and rather than going through getting them cleaned I was thinking about just getting some new stock ones to replace them with. My question is, if I get new stock injectors, will I have to get it retuned? Or since they are the same can I just install them and drive off? Thanks in advance for any help!

[EDIT:] Car is a 2005 STi, stock EJ257 motor except for a Spectre cold air intake and a GFB Respons BOV.

As long as it is the stock injectors, no need to retune. Ultrasonic cleaners are relatively cheap now on ebay and Amazon. My advice would be to try that first, before replacing.
