under parameters > fuel trim

old settings stock 240 , current 440

I changed it to stock 240 , current 1000
the fuel tables stay the same , do I have to scale it myself?

No, the fuel tables are adjusted by the injector size, so they should not change.

fuel trim does not change the fuel tables. Tables will have to be changed to suit the needs of the flow characteristics of your specific injectors.

After changint he setting in fuel trim, you will just have to begin modifying the fuel tables. You need a wideband to be able to read the AF ratios.

ok, I have a plx m-500

just thought it would do an auto adjustment so I don't have to guess the startup fuel portion of the map

Is there default multiplier you can use for each size injector, or do you just keep increasing until you get your desired A/F.

What does changing the injector size do if it does not change the fuel tables?

Changes to the injector size make invisible changes to the overall fuel trim.
