Hi, has anyone had any experience with diesel tuners-Tunit, they have a new digital tuner for the 170 cr which I was looking at (195bhp/288 ft/lb). Dont want to go down the re-map route as I've only got the car for 12 months and so would like a performance add on which can be removed and either px'd or sold on to recoupe some of the cost. Recomendations/ experiences of other chips or boxes would also be appreciated.

This engine has only come out recently.Stick with it as it is would be best

At the moment its to early to tell what tuning boxes and remaps will do to the DPF in the 170 cr. The 170 PD does not map or take to well to tuning boxes because of the DPF, the same might be true of the CR version.
