I am also in Somerset and have just got back this evening from AHM having had a remap/DPF removal on my 2.4
Brera which I bought a week ago.
First impressions are that it has improved the cars performance by a worthwhile amount making it much more drivable with quicker pick-up, better acceleration and no flat spots.
As a bonus it also feels quite a bit smoother and seems to pull better even in 5th and 6th gears at cruising speeds.
It does puff a bit of initial smoke on hard acceleration but I was aware of this and preferred this to cutting back on the power.
Still to early to tell if it improves MPG but hopefully this will be an extra bonus.
I combined the trip up to AHM with a weekend away and Adie let me have a courtesy car for the day and also fitted a new bonnet badge for me which I supplied FOC.
All in all excellent service and a good product, well worth the drive up if you cant get it done closer.
I am also going to be needing a new cam belt pump fairly soon so will look into getting it done with Duncan Slade, is he in Fishponds Bristol.
