I just bought a 09 with a PC5. I'm going to have it dyno tuned and the tuner said he would use the PC5. Is a TRE of any use to me? Why or why not should I get one? Or do I just need him to flash the ecu as well as the PC5? I've done some searching but cannot seem to find these answers. What else should I be telling the tuner? Thanks
