Default Injector help!

I have a 2000 JDM Forester St/b (ej205) with a VF48 turbo swapped in. turbo was swapped in at around 100000kms and the car now has 130000kms and bigger injectors have not yet been done. i am getting slight hesitation/sputtering under full throttle boost which tells me it's probably time to do big injectors which should have already been done.

My question is what size injectors should i go with??

Thanks a lot,

What are you going to use for tuning? Some methods don't support all injectors very well.
If going to a shop, see what your tuner wants to use on your setup.

You shouldn't have to guess about leaning out. If you don't have a wideband installed, do that first.
