I have the fuel pump tables showing with the default 33, 66% values.

Is there any harm or benefit from changing these values to 50% and 75% as suggested in the first post by the OP on a stock-fueling setup car?

Or is it best to leave these values alone unless swapping injectors, building the engine, etc?

Holy crap Oren, are you trying to set response speed records now?

Chuckle, no - you just caught me (successfully) trying to avoid gainful work.

Cruise: F0C5
Idle: F0D1

Both values at 50.2% hence the confusion
