The M5 has no upper vehicle to make sure it does not out perform. Why underrate? From a marketing/sales perspective it makes no sense. This car will need some marketing/sales push so this doesn't make any sense to me.
Also, I am still not sure about this bar $hit but if the stock motor is pushing 22 psi like people have said then how does this thing not have turbo lag? Will tuners be pushing 30+ psi? Doesn't that seem ridiculous?

It's economies of scale.
If this engine architecture turns out to have great real-world reliability, all they'll have to do in 3-5 years is bump up the boost/tuning to keep up with the competition. If they can just play that game to keep in the HP wars that means they'll get a lot of years out of this basic engine architecture, which means a lot of design/construction savings down the road. It also means they'll have that much longer to design and test its eventual replacement.
A much better path financially than building the motor at peak power now and having to completely redesign in to 3-5 years to keep up with the competition.
