You can flash a 335i with 335is ROM and it will get overboost.
It's just not something you really want. It's a bit like Turbo mode on intel processors. Just disable it and clock the processor up to it's stable max.
I doubt the Godzilla flash that BuraQ is producing uses overboost at all. All wedge was saying is that they can now manipulate overboost parameters.

So just to clear things up I asked BuraQ about how over boost works on their tune. Here is his reply;
"Overboost does one primary thing, it adds to Load target which adds more boost and other things. It is more effective in the low-mid end power range. I can dictate how much boost/Load I can add "extra" per gear, similar to what a piggyback can do, by using the overboost table.
Adding too much "extra" load/boost useing the overboost table than "necessary" can lead to performance instability. It has to be tuned for balance.
All N54B30TO cars that are tuned by us the overboost table is utilized in some way or another. So yes my Godzilla map does utilize the overboost table
Lets say I used the main Load Target table to target 160 in a certain RPM range, that gives me 13-14 PSI. I can an add an additional 20 Load in the overboost table to give me 180 load (gross) to bump boost, and other things, up to about 17-18 PSI in the specificied RPM range."
There you have it. Overboost does increase load of regular boost, and it was used on Godzilla.
Good news, don't you agree?
