Hi all,
After all the mods i have done, my fuel usage is obviously way out. A full take shows around 800km to empty, but i'm really getting around half that.
What do i change and how can i calculate what to change?
Factory injectors are 205cc, currently using genuine Bosch greens, which are 440cc, so 2.14 times larger. Is it as simple as making a certain value in the ECU 2.14 times smaller or larger to compensate?

be careful with the bosch green 440cc injectors some are double squirt i ran into this with a set someone had put in a vn v8 and i set the correct value for the injectors but could not work out why it was still over fueling.

The injectors have been great. Cars been running for maybe 2000km with them.
