I would be suprised if his diesel had an injection pump that you could adjust. Looks like it may be a commonrail injection which would be controlled by the computer. Not adjustable without some sort of computer.
I'd block off the intercooler to simply see if it does anything for your economy first before you possibly cock up a good car.
In consideration of the two engines seeming to be identical, woudln't simply getting the right parts be the best route? Might have to just change out the ECU and put in the wiring once you get the valve.
To be quite honest, I would put doubts on this helping economy at all. You would be warming up the air a fair bit, but simply staying away from the go pedal would accomplish the same goal. What's the listed economy figures for the 2 vehicles? I somehow think the newer one may be less efficient.
