I have for sale my DTUK CDT-T tuning box which is four months old, I am selling due to selling my car soon. The box has given me great gains in performance and economy and have seen gains of 10 mpg on motorway runs. The box is as new and comes in all original packaging with box and instructions. This fits most engines in the 2.0 TDI CR VAG range. It was fitted to my 2008 Audi A4 2.0 TDI CR. I am based in Hemel Hempstead and collection is welcome or I can post for no extra cost.
