Occasionally when accelerating pretty hard, I've noticed a "surging" kind of feel to the car.....kind of ...... non-linear acceleration.

Hard to describe really. Doesn't do it all the time though, only now and again.

Car is a 2004 MY05 Sti PPP

I get a similar sensation when accelerating in my car but that's a different story

Thanks for your help.

could well be surge - nearly all of them have it (to some extent) though it is harder to hear on unmodded cars due to the airbox. I was told this by Bob Rawle who seems to know a thing or to.

Aaah....so it's normal?

Will a remap sort it out, or is it just a characteristic of the car? Don't remember my classic doing it.

peculiar to that style of car Marty with the VF35 turbo..................

a re-map may make it worse at certain rpm's

Try cleaning the boost control solenoid and pipework with some brake cleaner, it may have some oil residue in it.

Aaah well.......I'll need a different turbo anyway if I want 380bhp!!
