Cheers Phil. I thought I'd do everything I possibly could without changing the turbo and injectors, as that seems like major surgery in my books.
Andy C has said its probably the best WRX he's mapped with the level of mods Ive gone for. Even he was surprised at the way it ate the gears as I piled on the revs.
I know its not a rocket ship compared to some of the cars on here, but I'm well happy with what Ive achieved for a relatively small investment.
Now I just need to sort a rolling road session at Motorscope to see what its actually running at.
