WHO TO MAP A VF9?? Postby Ashley g » Thu Aug 18, 2011 5:08 pm My car will be on the road within the next 2 weeks, and after running in it will need mapping. It's a fully rebuilt AAA with wossner pistons, ARP studs etc running either 8 or 8.5-1 compression. It's also got a VF9 stage 2 kit. Who would be best to map this? I know there's Stealth, but what about C2 motorsport I think they're called?? Or is it United Motorsport?? I'm in High Wycombe so wouldn't want to travel to the other side of the country if I can help it!! Does anyone know mapping costs too? Cheers, Ash
