so this is essentially a "hot" overrun. What % of throttle can be tailored for it. Using fuel or igntion or both maybe? More tech details please.

Funny as when I cruise I keep my foot covering the gas pedal slightly (always have done this habit) that keeps the throttle open a tad and makes nice burbling noises under decel.

This would be nice to have

I am using a combination of ignition, less fuel and valve timing changes. Wanted to avoid using more fuel and rather keep the fuel injection duty the sane and use the unburnt fuel more effectively.
This is where the valve timing comes in.

No need to use throttle opening
Actually defeats the point.

Does it need to be supercharged or can it work on a normal M3?

You would need neat fuel to kill the cats.
Long term they degrade anyway, especially the primaries due to the temperature.

No need to do a decat, there is hardly any power to be gained over high flow secondaries. Think close to 1hp.

Our supercharged cars have this built in to keep combustion temperatures down.

This feature is for NA cars.

yes, but I'm back to my OEM x pipe, so I think while it flows very well for an OEM piece the primaries aren't ideal

I want this. I plan on getting a tune in the next couple months and this is definitely something that will come into play when I make my decision!

Good work Evolve!

Sounds really good. Now, is this available only if you purchase the Evolve tune or can you purchase it by itself as an option for the guys that already have a tune?
