I have the blue spark tuning box on my 2.0 CDTI auto, and I have to say I've been impressed at first I had it on the max torque map and wasn't too impressed, but put in on the other map (think it was sport, or best fueling) and that is much better and has noticeably improved the performance and surprising the MPG (I think the mpg is also been helped with the pedal box).
I've had 3 cars mapped in the past a mondeo TDCI, Almera TDCI, and a Volvo S40 T5, and I have to say the best results were on the T5 that was a beast on the Shark remap but downside was it was £600 and ducked the clutch (although it could be argued that it was 75K when remapped so probably just shortened the life of the clutch, and was fine with new clutch), with the mondeo I had it mapped once, and it was a terrible map loads of torque down low then nothing, totally spikey power delivery, and again duffed my clutch, but got it mapped again with a DPF delete and the map was much better, power all the way through the range and added 41BHP.
But with Astra I wanted a just a little more ommph but I just couldn't justify the cost of a remap/dpf delete (was quoted £350) and although the mapper I used was confident I know others have had issues with unlocking/writing to the 2.0cdti ecu and he hadn't done an auto before.
Normally I would be really against a tuning box, but I had the chance to get one second hand at a really good price and thought might as well give it a go, and I've been impressed so far not an astonishing difference in performance, but enough to make a difference and make the car better to drive.
Like others have said I think petrol cars are always better mapped, as I think tuning boxes can do more on a diesel as manufacturer strive to get the emissions really low on a diesel and restrict the engine quite a lot as a result
