Has anyone used or heard of the company called SuperChips? Basically what they do is re-program your ECU to improve performance etc.
NB: I have a dual fuel Vectra which simply doesn't run quite as smoothly when running on LPG compared to petrol (new plugs and leads helped a bit but didn't completely resolve the problems), I'm thinking of trying these guys to iron out the problem further.
What I'd like to hear are any stories good or bad regarding the company and whether anyone has any advise as to whether this is a good way to resolve the problem (NB: it's gonna cost around £300 so if you think it's a bad idea please shout),
