I need help with tuning RXP-X260
I have a lightened 629 cam, Torx Racing ECU 9000rpm, Valve Spring & Retainer Kit Air Filter Kit
Also think and overlay an ET 68-140
But wondering if I should resort to RRFPR, larger fuel injectors and secure lot more but I'm a bit new to the game
So nice if someone could a little more about tuning can make any suggestions

You need everything listed and more.
First I would start reading like crazy here, also find someone near you to help.

Bigger injectors would be ideal but won't work with your ecu
AFR gauge and preferably a way to log

what is the reason that bigger injectors will not work with my ecu
what intercooler do you recommend

Vtechtuned is only across the mountain ridge from you in Sweden.
You really need to log your tune. Look on greenhulk performance store for the "logger" kit from vtechtuned.
Your injectors are near maximum on 3 bar pressure 8600 rpm.
If you run 4 bar, maybe you get lucky to 8900 rpm.
If I was tuning this ski I would use:
-Maptuner from vtechtuned www.youTUNEit.net
-Logger from vtechtuned
-4.2 bosch AFR sensor in exhaust
-RRFPR set to 3 bar
-1100 cc injectors from vtechtuned
This way you can edit and make your tune perfect.
Otherwise if you try tuning this ecu you have with just RRFPR, the ski might run funny with stock injectors and such high fuel pressures for 4.5 bar (rising rate absolute). You may also find you use a lot of fuel for no reason in certain parts of the map.
