We don't have any information on your vehicle so I might not be able to offer much.
What were the EXACT trouble codes retrieved? I don't understand what is meant by "charme pressure control" and am guessing it is something to do with the fuel pressure. If that is the case, this is the one causing the problem at high speed.
