Does anyone have experience of using this device, esp. on a Focus tdi?
I find that performance is very much enhanced, but at the cost getting only about 38mpg, plus a very smoky exhaust when accelerating.
Perhaps I've just got a thirsty Focus, anyway, as the consumption was only 2-3 mpg better before trying the T Box!

Sounds like this gizmo is doing its stuff but is increasing the fuelling excessively. I have not come across this paricular piece of kit personally. More info please?

you could well be correct - the car has always used more fuel than I'd expected, even before fitting the 'Box, which simply plugs into the ECU & gives a (claimed) extra 22bhp.
Only question is whether I can be bothered to remove it & pay for a Ford diagnostic test!

I have been in contact with the Belgian TB manufacturer, via the very helpful importer. They advise that Ford has experienced some problems with smoky exhausts on Focus tdi's, apparently traced to the Exhaust Gas Recirculation (EGR) valve, and that some dealers simply "disconnect the pipe at the vave" (!)
I was again advised to get it tested & report back.
Has anyone out there had problems with smoky Focus diesels?
