Just looked again, if your pump was forwards a spline at those sorts IQs, you'd actually make way more power, since you can have the max fuel screw out more, you'd be tensioning the governor more, the reason the power drops SO badly is nothing to do with the turbo, that's all down to the fact you're placing next to no tension on the governor spring, therefore the flyweights are pushing the levers back stupidly easily...
I wouldn't expect to see the *power* drop off anything like as soon as that, you can even see how quick the turbo comes in at 2400rpm, but as soon as the party starts, the governor is cutting the fuel back and the party is over - that's all by around 3300rpm!!!
If the governor stayed put and allowed the fuel all the way, that'd produce one of the best power curves ever, the torque comes in at 2.5k and would probably stay until 3.5k, and the power levelling off until 4.5k... As you can see, this involves no more fuel at all, just the same total IQ staying until higher in the RPMs...
