    Balancing MFI Airflow tool question

    I'm a total newbie at this but want to properly balance the airflow of my 911S stacks after installing a newly rebuilt MFI pump. Ive never used a syncrometer before so could use some advice on what would be best to use.

    Any advice would be appreciated.

    Thanks,
    Rob

    This one might be easier to use. Its close to what is in the CMA manual.

    My STE SK model synchrometer fits the plastic stacks and the throttle body bores of my 72 just fine.
