On the 135i yes, on the 1///M - sadly no.
Most tunes are well below 50whp gains (all else equal) on the 1///M. With Cobb, I had a meager 10whp peak gain, which incidentally is exactly as they advertised (4% gains), so at least full truth in advertising, but short of what one would reasonably expect for a tune on a FI car. TQ gains have been prominent with just about all tunes, HP is where the boys are separated from the men...
