The 130i, NA guys are missing the point. Whether you gain 7Kw or 10kw or 17Kw is neither here nor there.
Your actual gains are in the areas of improved throttle response, better fuel consumption and a smoother power delivery. Some tunes like the Rennzport offering provides extra features such as extra maps and the choice of switching back to stock map in seconds. But you not going to get the gains that are acomplished from diesel or force-fed motors.
Forget about major power gains for an NA car even with decat and filter. Great sound certainly.
You will have to consider supercharging or turbocharging to get serious gains. :thumbs:
