I put one on mine the other day (300tdi) and its noticeable! Much much smoother and picks up speed a bit easier... I.e. it seems to rev a lot more freely!
just checked mine that I removed yesterday, actually seems jammed shut! Your explanation fits very well with the engine becoming smoother at part throttle, my engine used to "hunt" slightly, it's now pretty smooth.....much better
If its that noticeable I'd suspect your EGR was faulty does it smoke any less?
I'd imagine that it was faulty yes... And yea it doesn't smoke much when I give it some stick now which is disappointing as it satisfied me greatly covering inconsiderate cyclists and taxi drivers in and around london!
That's a job on my to do list... Not gonna wind it up "too much" though...
