Just wondered if anyone has any thoughts or experience of the "CRTD2 Diesel Tuning Box" from TDI-Tuning

Have had my TD5 remapped my mike@dynachip but thinking about a tuning box for the TDV6 and this one came recomended..

Just seems to be a lot more adjustable with the option to choose between a number of preloaded fuel maps.. and pretty impressive stats if they are to believed + similar price tag to a remap my Mike too..

Any (well maybe not any) thoughts appreciated..
