My car is a CCWA so comes with a CP4 hpfp they run 1800bar stock. I've changed it to a CP3 NOT CP1.
Your car has a CP1 which is R85
CP3 runs 1600bar stock and is a R90
Before changing your pump you should ask your tuner if he can tune it.
You will get starting and running issues if you just swap it over.
However, as I've said previously R85 is pretty big pump as stock and shouldn't need upgrading for a hybrid based 2260.
I strongly believe you has missed maps in the tune.
