I am considering a remap to my 2007 A8 3.0 TDi, and have looked at 3 potentail companies: REVO, TOPHtechnik, and V-Tune. In the case of TOPH, they can provide either a tuning box or a remap, both with simila increase in performance (c+45bhp and +65Nm).
Has anyone any experience with the any of the above, and if so any feedback would be appreciated (or opinions if I am doing the right thing).
