any body fitted a engine remapping box  on a diesal engine

I have, DTUK CRD-T+.

No regrets.

And me - a Chip Express box - no regrets either

I was thinking of getting a Chip Express box. What are your thoughts and findings using it.

The acceleration and torque increases are immense (and I have not used the maximum setting either) and the improvement in MPG a really nice bonus. You also have the added advantage of being able to remove it and get it reprogrammed for another car in the future if you wish, so it has some RV. Additionally I've found the Customer Service before and after purchase at CE to be excellent, the units are well made, it comes with a 36 month warranty and they have a money-back guarantee if your not happy with the improvement. I'm really happy with mine...

I had the turbo hose go after fitting one . I also fitted one on my vivaro, went ok for a month but then started belching black smoke so I took unit off and took it back to the dealer ( as it was still under warranty) , they checked it out and when I got back it was running great.so I never put it back on

Not good. What make did you fit? Did you speak with them about your issues, or to get a refund?
