Might be a strange question..... and not sure if in the right section but....

If you change from say a 19lb inj to a 24lb inj, does that throw your trip computer out/make it inaccurate?

If so, can it be fixed with a tune/inputting a different parameter into the ECU or trip computer.

It might sound a bit prissy, but i like s**t like that to work properly!

The ECU needs to be recalibrated to suit 24lb/hr injectors. Beyond that its not a major problem. Bosses' 600+hp TE50 still has working trip meter, cruise control, A/C and 'Distance to Empty' functions.
