surely, the remap vendor is only important if you buy a generic map. If you go for a custom map then, agreed, it will be based upon the generic, but the real skills are down to the operator on the day...
can anyone also comment on the best time of year to you have your car remapped, especially standard ones (i.e. no fmic or cooling mods). I'd have thought that the ambient temperatures would affect any map and BHP gains (and hence its drivability). Ideally i suppose a normal (haha, define normal) day would be best?
