I assume these are larger injectors. If anything, I'd assume them to run rich if they were were plugged in without a tune.

TTT for you.

your pcm needs to be retuned for the larger injectors.

taking from an 03 and putting on an 01 may not be the same type of injector.
I know on these trucks on stuff is changed every 2 years, it is 99-00 then 01-02 then 03-04 even the 05 is slightly different then the 04
