Either way... that's good for at least 50 hp..... probably more as they fine-tune it and provides updates and new maps.
Or.... get it professionally dynotuned. As soon as I get to 10k miles and 2 oil changes.... I'm bringing my M50i up to BRPerformance Near Antwerp (I'm an American living in Belgium)..... and they have already tuned 1 M50i.... and were able to get 680hp, and 850 Nm torque.
Now... I know you aren't in Belgium... but there are tuners in the US... just gotta find one.
These guys have facilities in Dubai, Netherlands, Belgium, and a few others I believe. Good guys... already spoken with them several times. If they can do it... so can other places:

Both of those you mention above are piggies. A lot of guys would prefer to avoid the piggy solution if a flash can be done. I have read that some are bench flashing, but not customer held flashing devices. We need some of us to pursue this to get more info.
Terry from BMS is good. He has been turning the N54+ for a LONG time now. I am sure he can extract solid HP, but probably needs a test mule that is close to him or will provide him with a lot of logs.
