a unit called the spider was mentioned some months ago by nate 73 who i think has since defected to audi,i don't know if he ever installed one though.
I have this unit installed, did it on sunday. Makes so much difference. You can feel the extra power, the car has less of a flat spot before the turbo and the torque is awesome, just testing the mpg at the moment. So far im averaging the same but havent really drove economically yet, although i did today and was getting in excess of 48mpg
but did you had a 5th Injector recall done? i had my done and the flat spot problem seem to be gone, so unless this device make it alots better even after the 5th injector recall, then i will question if its money good spend. also which one you fitted to your car? Spider® diesel tuning system or the Venom system?

the unit took 10mins to install, its the spider unit which constantly updates to provide performance or economy depending on how you drive. You simply connect the unit into the common rail socket and attach the unit to the battery and your done, all instructions are included. I havent had the fifth injector done, my 220d is a 57 plate. It still has the turbo lag at low revs but its so much better now than before and im afraid that 6th gear is still quite poor, however there is some improvement. Im off to London today so ill let you know what the mpg is like after the journey. I drove through Notts yesterday though and was averaging 48mpg.
