Took my 2011 A7 into CAT for a DPF assessment and then they fitted in a stage 1 remap which was really good of them. They done a fantastic job, car is performing like never before. Now pushing out 310bhp and so smooth and responsive. MPG has also improved from average 36 to 42 which was nice bonus. Be going back for servicing and all future work.
