They are a very professional company from what I can gather..I have a full and very thorough inspecion report from them...quite an interesting read!

Not heard any complaints from people who have used them, like I said my car is set up by them and I love it to bits!

Not to say theres not plenty other good tuners out there too though..my mate's car was live mapped by Karl Norris and its an awsome machiene!, every bit as good as mine
