it's a 98my legacy twin turbo auto, and for some reason it won't rev much past 4k even if you try the kickdown so it obviously drives a bit dopey as it seems 4k is when the second turbo kicks in and i don't think it is.
now to throw you all a bit for some reason the car has had a gearbox change to a uk spec 2.5 box but nothing done to the rear diff so i presume the centre diff is having a hard time of it! would this attribute to any of the problems?
