PBox tuning. Just found in my Tourer. What is it?

[Joyful]

2006 2.2 icdti Tourer bought secondhand a year ago. I was just checking the oil last and noticed a box by the battery. The previous owner didn't mention it. It says (see photo) PBox Tuning cc. I can't find any reference on the web. There is a sticker with some details.

Any idea what it is and what it does?

It's a cheap tuning box, they usually increase performance rather crudely compared to a designated remap. Is it running ok, pass MOT ok, MPG ok?

Car runs ok and passed last MOT. Fuel economy seems very good for 2.2 litre. The onboard computer is showing 52.4 mpg which I guess might be an overestimate.

I'm sure Fahad will have something to say but you've been running it for a year and it's causing no problems there doesn't seem to be much reason to remove it.

Most likely plugs into your fuel rail and manipulates rail pressure to create some power. It will be causing inaccurate mpg readings as a result and also pushing your fuel pressure outside it’s normal safety tolerances to make the power. I’m not a fan of them but if you’re happy with it, keep it on.

Car runs ok so probably best leaving it on. I don't overstress the engine anyway around the Devon and Cornwall lanes and the 'safety' cameras on the better roads.
