Worth a punt for extra grunt?
Sir Tigger KC:
My old 1999 BMW 530d had some sort of box plugged in and it pulled like a train so I left it alone. :y

Which XF does he have Rae?. Diesel, or one with a proper engine. ::) ::) ;)

He has the 2012 xfs diesel decatted and de dpf nice dollop of torque there Mal but a short lived power band. I had the Evo properly mapped on the rollers with a good tuner I’ve known personally for many years and we tweaked it on the road with det cans after. I’m running 1.75 bar with 8.8.1 comp ratio but with lots of supporting mods too.

Those type of numbers were frequently seen from 2.8 Saab 9-3's on the uksaabs forum with no issues, so I'm sure the mighty Sig can handle it.
As others have said, I'd go for a proper remap though. :y

Looks like the people who sell the tuning box are fibbers. :-X :-\
Interesting video if you have the time to watch.
I've sent an email to Celtic for more details and cost. As others have said a tuning box seems limited as to what it can do.
