Hi all

Am looking for some advice on an appropriate Tuning Box for my 3.0V6 CDTi Auto. Car was registered in july 2005 so think it is 184bhp Standard. My main reason for fitting a box would be to try and increase fuel economy and would appreciate some advice from anyone who can help. Have seen that Diagnostix are doing a deal for members on a Powerklick green box but dont know if this is the best option. advice please
