Any indy or OPC can code it .. indy is obviously cheaper .
Fuel gauge if a C4 needs calibrateing .. again indy is best .
Sorry for the bad news .. i know i struggled to get the Boxster one appart .. but i had nothing to loose and was interested .
Cost .. hmm .. not that sure .. i would have thought 0.5 - 1 hr for codeing .. it depends on the indy .. helps if your a regular customer , garages try hard to keep their customers .
