Sure I know on a modded car, especially a turbo one you can turn the wick up all you want, but if my car is mechanically set up to be a "128i" and just detuned for marketing reasons.. Well I might be inclined to load software that gives me it's real potential
That's my question also. A year ago, I was convinced there would never come a 125i. Since there is no point at all to deliver exactly the same engine at exactly the same production cost with the same fuel consumption, with a tuned down software just to keep the food chain within your line-up intact. While you abandon the opportunity to shake up the competitive field seriously by not launching a 128i!

Besides, there is still some air between the "virtual" 128i and M135i I guess. Look at the 328i and the 335i, although here the gap is a probably a bit too small. But also here, they have chosen not to have a stronger 335i installed (why!?).

Anyway, I don't like to pay big money, having the idea that they could have opened the tap way more for exactly the same money just to have a defendable position for their top range models.
