low power and power surges at high revs

i have a subaru 2000 turbo, uk spec, the only mod has been a dump valve. when i got the car 4 years ago it was very quick, i now have a problem that i hope i can be helped with, a few months ago i first noticed that when accelerating hard, the car seemed to surge(like backwards and forwards). this gradually got worse. it doesnt feel like a misfire to me, i do little miles in it and mainly short journeys in it, a lot of which is in traffic, its only done 41k, the engine sounds sweet and doesnt smoke, i serviced the car last week and it seems a little better but nothing like right..this might sound daft but does little use affect the turbo?

sound like you dump valve may be on its way out bud,put the O/E one back on it....its also very advisable to "warm" her up before hitting that loud pedal hard,as the oil flow will reduce turbo wear..
