Not much difference in feel of power in my case. The exhaust burble is definitely there and it wasn't before, so I know something got updated software wise on mine, but heck in terms of power increase I am really scratching my head. The power delivery is more linear than it was before, but it doesn't feel any stronger - just smoother. People say 20hp is hard to feel, but I would disagree with that... its technically a 7% increase over stock and that shouldn't be hard to feel if it was really there :-)
Another good way to confirm whether you have the ppk installed properly or not might be to line your car up next to someone who does or doesn't have it and just see what happens. Unfortunately I don't have any buddies with another 135i m-sport package.
