Re: super unleaded Brera / 159
The GTA engines defintely do take (limited) advantage of higher octane even without a remap.
The amount of advantage they take when higher octane is detected can explicily be heightened by a remap while still accepting 95 octane if required.
This info is direct from somebody who tunes and maps Alfa engines for a living so I am pretty sure its on the money, we were talking about the GTA explicitly at the time but while I didn't explicitly ask - I got the impression that this would be the case across the petrol range.
RE new engines for Brera et al, I can't see it being any different
but the users manual should tell you whether higher octane is a waste of money, or, as in the case of the GTA to use "at least 95 octane".
As to whether you notice a couple of a percent extra bhp is a different matter

So do the "new" engines have the ECU whatever tht is that adjects for thre octane which sems to be a factor in whether an engine can make advantage of super unleaded.
I'm not a doctor - but I really do recommend braking later
