It is not unusual for a stock 930 WUR to "fog" under boost as the A/F ratio drops in the 10s. If that is your scenario and you also have a fueler then the situation is made worse.

If you have not done so you should check your A/F ratios on a dyno or with an LM-1 or like unit and adjust accordingly.

Personally I do not care for the ANDIAL fuel enrichment device. Those three fellows are experts but this device is often used when not needed. A more viable solution is an adjustable WUR.
