Hi,
Came across the forum as I was searching for Jag. tuners and read the interesting (but old) thread about it on here.
I used to own an old X-type for many years, but when I kept having to clean out the EGR valve regularly decided to go up to the XF (last year).
I now have the XF R-sport (black edition) 2.2D
Great car, but as I have been reading on here, it does have the problem with lag on acceleration. I am just awaiting a reply from a local tuner (quantum tuner in Coventry) to see if a re-map will help with the problem and how much it will cost.
My other car is a modified Toyota MR2 roadster which I do the show car circuit with (so not a daily driver!)
