So now that the ecu issue has been settled, is there any reason to take a look at our mass airflow meter rules? I had a new ecu installed on my second gen and my builder said that there was no longer a need for the very restrictive internals in my MAF. He said it robbed as much as 4 horsepower leaving the plasic internals in but i told him to leave it stock and unmodified.

Why do we still have to keep that stuff in? or did i miss something with the rules change?
