Over the course of my time in NZ I had 3 twin turbo legacys (94 auto saloon, 94 manual saloon and 96 manual estate) and always wished I had a single and enjoy my 09 far more than the others. The single turbo gives a nice kick at a lower rpm range.
The smaller turbo on the sequential diddn't give the omgboost feeling I love so much and although the second turbo was quite a kick in the pants, it diddn't kick into so high of an rpm that I diddn't really get to enjoy it often in everyday driving.
Maybe that could have been helped with a tune, but I wasn't even aware that was possible until I discovered this place.
