If you want to try to fix this yourself then you need to start with Engine Setup

07 Engine is the section you need

Banks/TP's are out of sync.. Start with a syncrometer and set the throttles up.

Did you speak to Nev about this?

Have you really managed to get the water temp up to 120C, or have I forgotten how Aide's RS_AJP app works?
