Well, you do know that when you gain 20/32 at the crank, you gain just as much at the wheels? Stock N55 runs about 270 torque at the wheels; after tune, it averages close to 300. That's a very feel-able difference. On average, your Bimmer goes from 270/270 at the wheels - to 290/300 at the wheels. Give or take.
