i would recomend a tune, since it is the 03 i'm not sure if it is required to work right. most of it works off of the boost solenoid which controls everything through the wastegate unless u were upgrading the turbo to a big one with an external wastegate u shouldn't need a tune. but like i said i would still recomened it
