Thanks JDM_Style and Vyper,
Yeah, the exact and only mod I'm really after at this stage is a 3" turbo back exhaust to hear that "sweet as sex" boxer rumble, why else would one buy a rexie? but I've heard of boost control issues associated with that mod on the newer models and figured that I'd take the time to retune the
ECU to make sure I had no boost spike issues and pick up a few kW while I was at it.
