Apparently the GDI pulses fuel in at 2200-2800 PSI as apart from 600-700 on a standard engine.
This idea no doubt is to help emissions but would complicate the injection throttle body setup.
Not sure if they use the same system with the ecoboost but tuners are going to have their work cut out to get anywhere near the ecoboost figures.
I agree Peter, the older Duratec would offer a more straightforward tuning option, which is probably why Morgan looks as if it has gone for the Cosworth Duratec in the AR +4.
