The markets APR and Oettinger are aimed at are slightly different IMO.
Oettinger has better warranty and a slight more sedate image aimed at a particular demographic.
APR on the other hand has always been more aggresive in their remapping (when they don't code share with Oettinger:)) and in the GTIs has a characteristic "boost spike" early for a really aggresive feel.
Turbo cars though in general are peculiar in the way that they react to throttle openings (in comparison to NA cars). Having a boost guage fitted demonstrates this best. You could be doing 4000rmin at light throttle and the turbo would not be working at all. At full throttle at 4000rmin it would be a totaly different story. You learn to use this to best effect because when the turbo IS working your fuel consumption skyrockets.
Personally though, I'd wait for an APR remap.
