Have now had my tuning box for the past 2 days and must say im very impressed.
Have done some vcds logs and it's showing 169 Bhp and 260 lbft up from 138bhp and 236 lbft. This is only on setting one so will have a play around this weekend.
Chose the tuning box as I can remove it quickly for any warranty work or servicing. Also no one else can yet tune the 2010 diesel CR engine to have a removable map.
