Hiya, Im new to this and have only owned myWRX for about 11 weeks, Took it for a blast on Tuesday and when I hit 100mph it seemed as though the engine was missing, power, no power.. kept my foot down and it would'nt go past 120, I'm not a boy racer by the way lol, Turbo kicks in at about 4,000revs and boosts at 1.5 psi, dont know if this set up right, it's a 93 and i've been told that it could be the ECU and that year cant be remapped, any held i would be greatfull, thnx
