Citroen/DS Tuners/Re-Maps

[MikeyMike]

Are there any companies with experience of mapping or tuning Citroens? Not an obvious brand for modification (excluding the venerable Saxo of course), but the wife’s C4 Cactus with the 1.2 turbo petrol engine feels like it needs looking at. Around the time of the emissions scandal, Citroen issued a recall for a “software update” and i swear its felt a little sluggish ever since. Whilst I need to maintain reliability as it is our main family transport I do feel it could benefit from a tune up.
