And if the car has more than 70 thousand miles I would increase another 2psi pounds of boost, in order to make up for general wear and compression loss, as recommended by most turbo charger pro's.
And in the end have a mini cooper operating exactly where it needs to be for the mileage or the performance upgrades without requiring any type of boost gauge or re map of the DME or ECU.
*for further instruction on increasing the turbo boost, inquire on this thread or on the forum at a later time. I personally can do a walk through.
