Have finally found a tuner to remap dpf out of my 56 plate a4 170.
I removed the dpf myself as wasnt willing to pay £1000 to a few companies for doing the job. Dave at Rapid Remaps of Cannock did a Remap and dpf delete. I now own a totally different car.
8 - 10 MPG Better,
So much more torque,
Alot smoother all round.
