Default jerky comin on to boost w.o.t

As above, when I accelerate from low revs say 2k with wide open throttle the car feels lumpy up untill I hit full boosts at around 4k then it just feels fantastic from then on, its doin my head in, its not really jerky just feels like something isn't right, ? its a 2002 sti prodrive style with cone air filter and cat back zorst,

You are best off giving the MAF a clean first as a process of elimination, then clean out the boost solenoid. If the problem is still there then you may need to replace the plugs/leads etc.

what mods/ spec have you got?

Is the car mapped to the cone filter?
