Re:
I've had my chip express installed on the 2.0 for the last 6,000km or so.
Apart from installing it incorrectly to begin with (there are two identical plugs very close together, and the manual wasn't super clear, especially since you can't normally see the correct plug, and need weird mutant shaped alien hands to actually get in there), its all good.
Power definitely seems up a fraction, and economy is usually an indicated 6.8/100, but i normally get ~800-900km/tank city driving (7.2 - 8.1/100)
Overall, I can say the chip express at least, works as advertised. I had to 'race' a corolla the other day (how embarrassing), but i did manage to get ~2 car lengths ahead by about 60. I guess thats more than id expect from a small diesel.

Re: XTrail Diesel Chips
As far as I am aware, all of the diesel XTrail performance chips going around increase rail pressure to achieve results. They achieve this by sending a false signal to the computer.
For example, lets say the signal received by the computer at full throttle is 4 volts. The chip sends a 3.5v signal at full throttle, fooling the system into forcing more fuel in until a 4volt signal is received, which increases rail pressure.
Not only is this an agricultural way to deliver power gains, it's a VERY BAD IDEA as it will cause you problems before too long.
There is one exception, a Chip My Diesel (CMD) chip.
Instead of primitively increasing rail pressure, the CMD chip monitors & learns from your driving style and inserts extra fuel pulses, whilst maintaining factory rail pressure.
It is 4 way user adjustable accross 4 RPM sectors
General
Low RPM range
Mid RPM range
High RPM range
If you are considering a chip for your XTrail diesel, I'd start and finish the search with Chip My Diesel.
