    I reached to a point where I need my ViPEC to give me a little more ...

    I need more boost, better timing and richer AFRs ...

    For AFRs, is this right?

    Just some help:
    Make sure you understand what it is the table your changing does. Yes it sets the target for AFR .....BUT it also changes the injector pulse widths on the main fuel table when its values are changed.

    This table functions in several different ways. The intent of the table allows for fueling adjustments to be made on a tuned motor just by simply changing the AFR numbers on this table. It also provides a target for the Closed Loop Lambda system. The reason I'm say this is, if you have made changes to the Main Fuel table and then changed this table you will have unexpected AFR values. I would recommend that you proceed with caution if you are running a larger boost wheel then what the file was originally setup for. Best practice here would be to make small changes and all ways refer back to your O2 sensor data. Also note the max boost values each table has been set to.
