If you look at it in detail, you will notice that the limiter should be at around 5750 rpm. If Morgan did de-tune the engine via mapping, it should be enough to just flash the ECU with a normal mapping to get it up to its full potential.
The question here really is: why would morgan de-tune the engine? Is it the beltdrive that can't take the power? I think I remember some issues about that, no?
Upping the power could be dangerous for you car and even yourself if something was to go wrong with the rear wheel, so I suggest that someone tries to get some information from the factory about if they de-tuned it and why.
