Anybody done this, what did you have to upgrade apart from the following:
turbo
downpipe
manifold
injectors
oil & water feeds
When changed over will the car run without a KO4 map? Who is the best person to get a map done by? I have got a map done for my KO3s will the KO4 enough for gentle daily use until the KO4 map is done (a week)
Thanks
