We have a 2.8 JTD like you, it had done just over 4000 miles when we got it, and we had similar performance to you. Ours is a low profile Rapido so we have less wind resistance than you. We are up to nearly 8000 miles now, and can notice the engine is starting to loosen up, and it is revving more freely over 3000 RPM. There is also an improvement in the general drivability with less downshifts to maintain cruising speeds. I would guess that your motor is OK, I am sure you will see an improvement with more miles on it. Remember it is only 127 BHP at best hauling 3.5 tonnes, with the engine still tight you may only be getting 110 BHP. That's about the same as my 1 ton Astra with about 1/5 the frontal area!!
Get a chip if you want better performance, but wait until you have some more miles on the clock and you may find you are happy with what you have got.
