Re: UrQ Overboost



Andrew,
We still need a base line for your performance, how much boost were you
running successfully before the problem of cut out?  I think the number (7)
indicates the heat range for Boschs, therefor the plugs you swapped are the
same heat range, if you think its the plugs simply swap the others back in.
The US Audi introductory service manual list the Bosch WR5DS as the correct
plug (.o28gap), as the Silvers are expensive/unobtainable most go with the
WR5 Coppers.
