Not so much. BMW only gets you to 18 psi at altitude. Using the common, good-to-6000-feet "standard" that most manufacturers use for overboost, plus the rule-of-thumb three percent loss per thousand feet of altitude, you can look for a gross power gain of about 18% if you run 18 psi at sea level, which should not overtax the turbos at all.
Let's see. Eighteen percent of 425 horsepower gets you, hm-m, carry the twelve...
Wow. Even with additional heating due to increased boost at sea level, an additional 50 horsepower seems as if it would be a walk in the park.
I bet they'll get even more than that.
