what areas of my car would need upgrade after I chiptune the diesel from 163hp to 197hp, and torque goes from 340Nm to 400Nm. Are brakes on 320d good enough for the power increase, is the steptronic transmission gonna be OK with it? Anything else worth thinking about, or the car is built with some performance surplus so to say and can handle power increases ok without changing the components? it's not so big increase come to think of it, but I thought I'd ask the people who chip tuned theirs...
