I think about one thing...I have Leon 210HP and I compare maps KFMIRL,KFMIOP,LDRXN with Leon 225HP and only LDRXN are different.
KFMIRL and KFMIOP have the same values in 210HP and 225HP files.
So when I want more boost maybe only LDRXN I can change and its enough? I have K04 so I can raise it from 0.8bar to 1.2bar?
That's because they are essentially the same engine.
To put I simple, yes LDRXN would be enough for 1.2 bar boost.
But don't forget to get your fuelling sorted.
