Without sounding like an old stick in the mud, perhaps a WRX forum
is not the place for this question. Imagine what would happen
if I asked about a verso tune on a 05 STi on a RAID forum !
Yes yes, it is the "non-wrx" section, but it is quite technical. Do you
really want to take RAID advice from your Mechanic. Does IBM service
your WRX ?
Try
HERE to get a better understanding of RAID.
Then perhaps search the google groups for answers
