Correction I thought that car had a n51 engine and it doesn't. That was on a non disa n52 model. My apologies. I miss read his email. He said with the addition of the disa manifold I should make more power than the dyno he sent me. It was my mistake not his.

And if the 125i has the n52 why does the dyno show typical drops in torque and power that is characteristic of a disa manifold? Is it because the n52 is tuned for the disa but doesn't have it installed from the factory?

I don't know much about bmw's. Help me understand.
