Look at your TAC a little closer and I think you'll find the part number to be 12573059 rather than 12575059. If that's the case, then it should work. That TAC is for a 2003-5, so you should be good to go. To run the flex injectors, you'll just have to let your tuner know it's a flex engine, and of course the harness will need to be flex fuel too since the plugs on the injectors are different from the non flex.
