Hi All,
I thought I'd join thanks to Naths link and me not being able to stay away from Fords!!
We (van Aaken Developments) specialize in Turbo Diesel plug in upgrades and certain Turbo/Supercharger conversions. We have moved away from the RS scene unfortunately. Working with RS's was one of the main reasons why I joined them so I am gutted but we have to move with the times. We are now one of the few turbo diesel upgrade manufacturers who have a big name in the USA and around the world. In the past I have used interpro in Bristol and have always been pleased with their work. You sometimes have to travel to get a decent job done, or if you have a local RS Ford dealership they sometimes have a trained RS technician whos a bit handy cos he will be the main man for working on any RS that comes in.
Sorry we couldn't help
