Opinions on TUNIT box

Hi all, Just got myself a 2003 2.7TDi LWB Terrano. All good bar a few little areas of bodywork welding required, although I'm now looking at improving the fuel economy by fitting a TUNIT box. What's peoples thoughts on these?

Do they improve the MPG noticeably? Or is there a better alternative out there?

Cheers all.

Hi mate, yes a tunit box will give an increase in power or fuel economy, never owned one myself but reports are good, Riick
