The little box for more power tune, as it gives more power dose it give more MPG? and is it worth the cost? (around £300 or is there cheaper out there?)terry7

There is probably some cheap alternative on Ebay. It will probably break your engine.

Buy the expensive one. There are plenty of references on this site about good ones to buy.

If you want more mpg, change from 270CDI to 220CDI or 200CDI. These boxes will almost certainly not help increase economy - any gain will be small and it will take an age to recover the initial purchase cost - Chances are that they will increase fuel consumption.

Its also worth having a look at www.dieselcar.com/ as they have forum pages even dedicated to particular marques of deisel motor and are always chewing the fat about tuning boxes etc.
