it increases, just like others, its actually a smoother powerband, and i'm not reving it for the hell of it, if you'll ready what i said it stops making power at 8300 my power doesn't begin to fall off until around 8700ish and even by then i've only lost 1 hp until 9400, i just reved it that high to rev it..it seems to be making more power.. and no the car feels strong at some points..
