Bigsaint said:While we are on the subject, I've heard that Yoshi maps, at least the ones provided, are only set up for their exhaust systems, is this true ? My biggest concern is buying the ems only to find that a dyno center that deals with them is non-existent. Anyone ??? My real question is what will I be up against, if I go with either a Hindle or Akra full system and the ems ? I like the map availabilty of the PC3r, the complaints of problems and performance is what concerns me most.
