2009 sti maf scale

Hi all,

I have a 2009 sti with simple mods, TB exhaust, boost selonoid, 16 psi wastegate actuator, fuel pump, injen cold air and big maf housing etc. I re-scaled the maf sensor without any problem. My car goes 19-20 psi with stock turbo (vf48)

Now I am planning to install tomioka 20g turbo and id 1000cc injectors. my question is do I need to scale maf again after installing turbo and injectors? I dont think so but I fell suspicious and I want to be sure somehow.

any help will be usefull and appreciated much. Thank you.
