the car will be chipped m8 the standard ecu can only run arround 10Psi of boost before it cuts the ignition.
The actuator you have is a big collins one.. IMO they are crap compared with a propper -31 but lots of people still use them,
! bar of boost is likely to be perfectly ok on your car HOWEVER the ke-jetronic fueling system willnot fuel correctlky for anything other than standard boost without modification.
becuae the car runs a bit rich from the factory then it is likely that 14Psi will be fine... BUT for piece of mind i would get the cars on boost fueling checked and/or the ke system modified accordingly
