Just changed from a 3.0TDi A4 that had been re-mapped (270ish BHP) to an A6 3.0TDi (230BHP) and it feels a little sluggish although smooth as it does not rip your neck off like the A4 did.

I am going to get it chipped one way or another but is a remap that much better than a tuning box and also whats the difference between a cheap box and a digital tuning box?

Answers on a postcard please............
