Hi.

Can anyone help me what can be wrong with fueling after change fpr from 3 to 4 bar?

No tvub didnt need to be changed.Injectors are stock. All trims are perfect
Idle -0.2 part -0.8 only problem was with wot fueling but i solve it because i think its fpr fault or stock fuel pump cant hold 4 bar on higher flow when engine is in wot and I do some test but i think i have found problem.
