Always up for a bit of trial and error so just keep me posted. Last week I dropped off some spare injectors and new bigger nozzles to a local specialist to rebuild/ balance and most importantly play with the opening pressures. We'll then see what happens.
Regarding the graph I can see what you mean from how it looks but actually (and I agree it's a very personal/subjective thing this), having come from naturally aspirated petrol engines which all like to be thrashed to make progress (cammed v6 race car, v8 ZTT and recently added vx220), I actually like the linear power curve. There is something satisfying about building the revs and the more you work it the more power you get. My hardcut is set to kick in between 4800 and 4900 but you can see from the graph there is still over 190bhp at the limiter. Also, the fact that power and torque gradually build puts less stress on the drive train.
That said, a huge lump of low down torque does make the car feel "muscular" and with a vnt, assuming it can be properly controlled, I guess you can hopefully make it cling on to the top end too and have best of both worlds.
My 330d always felt like that, a low down hit but still pulled and pulled up to the top.
Hopefully you'll make it to POL or similar at some point as I'd love to see how they drive differently.
