The mapping for the GDI engine is very complex stuff and absolutely not something that can be undertaken by a "tuner". As far as I can see from the various reports the original mapping was not really very good for the Morgan application. Everyone who has had the later mapping installed seems to be very happy with the results. This leads me to believe that it should be performed on all cars with the earlier mapping (or calibration).

I am not clear if there are two separate calibrations that can be installed: one for the standard set up and a different one to be used with the sports exhaust system.
