nothing

Answer

hello. the computer is the same for both vehicles.... BUT the computer will have to be reprogrammed to operate the 5.3 properly. there are "calibrations" stored in the PCM (computer) that are different for each engine. a local shop or dealership can program the PCM quickly and usually fairly cheaply.
