Re: Impreza engine management?
There is an Australian tuner who goes by the user name of throttle happy. Google him on Subaru forums and you will find plenty if not all, who are very happy with his tunes. He has worked on the newer Imprezas and has commented that there is not enough 'wiggle room' to make any noticeable gains. Seeing as the XV will share identical if not close tunes, then there is another respected tuner that concurs with others, theres not much to gain with the newer ECU/ECM's.
