He's got mine at the mo', doing a service and mot stuff, but when he's done that I was going to talk to him about tweeks. He should be finished tomorrow if the new cats come in, so I'll talk to him and let you know.
Spoke to Peter today and he doesn't do re-maps so you'll need to look further a field I think. I'm thinking of taking mine to "track car solutions". Bit of a journey but from what I hear Jules knows his stuff and it's worth the trip.
