Hi,

I've got a 2012 A6 S-line Bi-TDI avant, I've fitted it with a TDI tuning twin channel box and set the box to max, the problem I'm having is that when auto is engaged in dynamic she hits the rev limiter when I floor it, which clearly doesn't happen without a tuning box fitted.
Why is this happening, if too much power then TDI tuning are selling a box not fit for purpose, I have actually spoken to them, they have told me to return the box and they will re-map it, does this mean reduce the power in the box? Which I don't want, as the whole reason for buying the box is for more power/better MPG!
Or is it a DSG problem ?
I know if I change gears manually there will not be a problem, however what I don't want is for my wife to commit herself to an over taking maneuver in auto, then loose power at the point of no return and potentially have an accident.
I'd really appreciate it if anyone can help.
Cheers
Ian.
