Either will be fine, just curious as to why the different part numbers and pictures of different injectors ?

Toni,
just remember, when you do fit your new injectors, you will change the req_fuel setting appropriately, but the whole VE table will need re-tuning.
In theory this shouldnt be the case, but it always is as injectors opening time characteristics change at different opening times, and the spray pattern will be different.
So dont just jump in it and start driving as you had been, start by logging it and keep out of boost until you get a feel for what needs changing.
thanks
Phil

Can't you just increase your fuel pressure?
The 044 should have enough headroom shouldn't it?

Depends how much headroom you have or need. But it would be a free option.

And how much more fuel do you need ?

Wind base up to 65 or so. At 10 psi boost, that's still only 75psi tops
