On a side note, doesn't surprise me we see another FI motor being underrated from the factory.
FI engine are more effected by heat so they are tested to meet quoted output at high temps up to 35c, so the lower you go the more they produce accordingly. The only thing I have wrong with that report was the percentage of drivetrain lose, 20% is excessive for a quattro.
