Great write up Paul, and glad to hear that you've experimented with the various files too

The Mk5 GTi was the same - first few months, there were encouraging signs of the fuel economy increasing by 4-5mpg - then after a year it started dropping below 20mpg!
My 330d has a tuning box also, it has managed a consistent 38mpg around town and will do 48-50mpg on a 20+mile motorway run.
Personally, I can't tell the difference between re-maps and box's - in terms of power delivery. How good or bad they are for the engine is debatable - but I will say this, why would any company even think of selling a device with a 5 year engine warranty, or however long it may be, if they had any idea's it would damage the engine?

We dont offer a 5 year engine warranty, but do have product liability insurance in place, for an occasion that a module causes damage.
