Is my car ok boost problem?
 

Bought myself an impreza rb5 wrsport on friday.
I have never driven an impreza prior to buying this one.
It only seems to boost from 2500-5000 and then i feels like it is slowing down like it's holding back.
the car is standard apart from PPP and a bailey VTA dump valve

if the car is standard they boost at 0.9 bar upto 5000 rpm then drop off to 0.7 bar after that, sounds normal.

good that sounds about right just this whole turbo thing is new to me

sounds like the old td04 trait, spools very nicley, but runs out of puff
