RS2 Injectors direct replacement

[M0KK4]

Hello everybody,

i used the search but i can´t find any exact answer.

i´ve done a Turbo Upgrade from SMS Revo to TTH 7200-420 Turbo ( RS2 Turbo + Modifications good for 400-420 HP )

I´m running it on the old Software from the SMS Revo with about 330 HP.
Works fine so far.
But after the Quattrolegende Meeting two weeks ago my original RS2 Injectors make Problems.
I´ve planned to Map it in winter.
400+ HP is the target
And here´s my question.
What Injectors can i run instead of the RS2 ? 0280150984
I don´t want to spend 700€ for new ones and i wont take used ones

My options
The Bosch 440 0280155968
The Bosch 470 0280156280

Both EV6 .
I know they fit mechanically
but can i put them in and drive the car like the original RS2 Injectors or do i need to remap it ?

I Hope you can help me .

Best Regards Patrick

Hello,
After some mails with L-Speed i decided to buy the 0-280-156-280 injectors.
today i put them in and the engine runs fine with them, less Power because the air/fuel Ratio is not correct ( too much fuel) but for the new turbo i need a new map so it can be programmed with the new injecorts.
