2000 turbo Impreza...
No mods other than a cone induction kit, starts to run slightly lumpy at 3500 revs but really kangaroos at 4000 revs
I take it by reading through a few other threads the induction kit may well be the problem although its been giving me a few problems previous to the induction kit...
Secondly will this cause any damage if I run it with the induction kit on? or is the advice to revert back to the old intake? Dont want to fry a piston

What model year is it? If you're not sure have a look at the Applied Model code stamped on the ID plate on the nearside front suspension turret and tell us what it is. (it's the one that will look something like GC8xK8D).
Does it make any difference what gear you're in, or does it get worse/more prevalent in 4th/5th? Does it still happen if you accelerate gently (rather than foot flat) or is it still an issue then?
The induction kit may be a cause of or contributor to your current problem. Even if it isn't a factor in what's going on now, it is a potential problem area in the future and in the worst case scenario an engine breaker.
As you have already suggested, the best thing you can do with it right now is take it off and re-fit the OEM parts. If the engine is otherwise standard the aftermarket bits won't be doing the performance any favours anyway, the standard bits will be more than good enough.
Oh - as a risk mitigation measure, keep off boost until you've got this problem isolated too.
