1999 Forester S Turbo 5MT
Anyone (Simon) know what the maximum boost you could use on a UK 99 S Turbo? I know the ECU restricts it to 0.8 Bar but if you could get around the MAP sensor, say using a FCD, how far can you take it? I see people who say they are running 1.0, 1.2 and even 1.4 Bar, does this have more to do with the actuator once the ECU has been reprogrammed or internal mods? Ta.
