No negativity towards you intended.
I just don't want you to get your hopes up for what has been in development for 3+ years now. Whole bunch of tuners claiming to having chips for 325/330 a while back... got us nothing. No concrete dyno results, no concrete gain.
I appreciate you trying it out and reporting back the results nonetheless. I hope it really works this time around.

I have already visited the link you provided long time ago, and all of the links are either for turbo engines or 325/330. None of them has one for 328i. Plus, there's no mentioning of Powerchip in that link you provided.
I am not sure why you're so negative about something I would like to enjoy. If you don't like what you see, then just don't bother looking at it. There are many people, including me, who are interested in this stuff, and I just wanted to share the news with them. It's obvious you aren't one of them.
