530i tuning options
Has anyone here had any tuning done on their 530i? I know the little motor will never be high performance without a lot of money, but a little extra go would be nice. I see a lot of piggy back tunes and an ECU tune or two, and can these be dyno tuned?
I'm not sure what the possible gains are, I hear these dyno out at an adjusted 280hp factory, and piggy back tunes seem to claim anywhere from 280hp to 315hp out of the car, but I haven't found anyone really doing any dyno testing or even acceleration testing to confirm this.
