Took Dai's car for a quick blast last night and the good news is those fault codes have gone

Slight bad news is the 17963 - Charge Pressure Control - Upper boost limit exceeded has appeared for the first time since he replaced the MAP sensor

Occasionally the car would bog down slightly and then pick up and pin you right back in the seat. Logged block 115 and its always nicely above the specified boost pressure but is there such a thing as having to much boost going through the system?

For a Spec 1 map though it is absolutely rapid
