When I got that car, it had an exhaust system, hdi Fmic, It had a different turbo on it, I think it was either a 16g or 18g, probably 16g. It had been last mapped by Andy Forrest, and had 2 different boost maps that were selected by the re defogger button and the accelerator pedal.
I sold it to a man called I think was call Pat Drennin, and it went down to cork or Kerry somewhere.
Last I heard about the car was he had left it into to Subaru main dealer and they had erased the maps.
Whether they did or not I don't know, and that's the last I heard of the car.
It's a long time ago now so I doubt its same
