I bought new "larger" tires for my 09 Chevy 2500 . I see the instructions on how to change to tire size but do I need to reinstall the the performance program or can I just go in and change the tire size?

you have to reinstall the tune...

select the same performance tune you installed before... then select Modify Tune... then make your tire change... press the center button to save your adjustment... then press the ESC button until it asks you "Install tune now?" - answer/select YES and it will reinstall the performance tune with your tire change made to it...
