1.2 bar=17.6 PSI which is getting into that stock EVO territory. It's nothing like starting at half that as with the N54/N55. Then factor in the anti tuning strategy started with the N55 an plan on this one being even more trick. Sure, an N55 can be tuned, but it is a whole different story from the N54. Isn't the EVO at the other end of the spectrum where boost may be increased simply by fiddling with the wastegate controls?
I think this is a good engine, but I would not buy into it thinking there is an easy 15% HP boost waiting.

Sounds to me like the boost was not changed all that much but the mixture and timing get major changes. Whether the BMW turbo four has these characteristics is unknown.
