recently got my 998 on the road, at low revs trying to maintain a speed, ie 30 in 3rd, it judders, it is fine when accelerating but juddery at low revs, is this just the mixture ? if so is there an easy way to set it without a rolling road ?

Juddering can be caused by million things..is the car 'pinking'? what colour are the spark plugs?
Anyway by turning mixture nut clockwise you can enrich mixture, and see how it goes.
