I have a starex 2k model TCI engine. 6months ago i had my injector nozzle tip replaced at bosch banawe nozzle tip is bosch 130. Previous Fuel consumption before the replacement was around 7.5km/li but my ride was a bit sluggish. After tip replacement, the FC now is 6 to 6.5km/li but the power improved. I still feel that the FC is far from the average as some other starex of same engine and model even lower have an average of 7 to 8km/li. Should i have my injection pump recalibrated? FC is influenced by a lot of conditions: eg. road & driving conditions, average number of passengers, aircon temp setting, fuel injection pump settings, etc..... Your injection pump can be tested to verify if it's settings conform to specs, and/or adjusted as necessary.

My other concern though this is not bout fuel system but i would appreciate if you can advice me though, is that on highway when i reach around 85kph my tranny locks at override and its suppose to stay locked at that speed or above. The problem is i need to keep a press on the pedal to keep my tranny locked. IF i relax a bit on the pedal, it downshifts and the rpm increases indicating a downshift in gear. What do you think should i do? This is the first time I've heard of such problem. So I don't have an answer at the moment. But I can study this and ask around.

By the way, is your injection pump electronically controlled?
